presenting Mario Marzidovsek

Mario Marzidovsek, slovenian oldschool industrial/noise artist & yugoslav tape culture pioneer came from sedate and colorful little town of Slovenska Bistrica. He started releasing tapes in 1984, previously being a productive member of the mail art network. He released a tape for Staalplaat in 1987 under the pseudonym "Merzdow Shek" and appeared in various nowadays-legendary industrial compilations like those of Alain Neffe's Insane Music or Karsten Rodemann's Graf Haufen Tapes. Extremely prolific, besides his musical activities [and he did release an amount of some 50-60 cassettes on his own independent Marzidovsek Minimal Laboratorium label, thus encouraging the development of local scene] - he was also a visual artist, with a interest in painting as well as collaging and xerox-art and a performance artist, organizing a number of happenings and actions. He was also into visual and concrete poetry and wrote numerous essays on music and avant-garde art. A real allrounder.

In 1988-89 he aborted all his activities and moved to Netherlands and later Germany, where he even performed a couple of times, finally returning in 1991 in Slovenska Bistrica where he remained silent. Here's a shortened version of Rajko Muršič's excellent article on him:


"Mario Marzidovšek was a unique musician, artist, producer and organiser from the north-east Slovenia. In the eighties he was engaged in numerous alternative activities, including mail art and establishing of a first private - then illegal - and non-commercial label in the former Yugoslavia. From 1984 till 1988 he released more than 50 cassettes with various kinds of music, predominately electronic and alternative rock music. He established a mail network and communicated with numerous artists and producers from all around the world.

Although his work was partly influenced by the activities of the Neue Slowenische Kunst and other alternative groups and producers in Slovenia, his work was original and unique. His musical activities in producing electronic music were influenced by German Kraut Rock and various modern experimental composers. However, he supported activities of punk and hardcore groups in the region by his label and organised several important concerts in Maribor. In 1985, he released two compilation cassettes presenting alternative punk and hardcore groups from the region.

His electronic performances were noisy and radical. Although his cassettes were of bad reproductive quality, due to the poor technical possibilities, he was sending them to different addresses in the former Yugoslavia, Eastern and Western Europe, United States and elsewhere. He released many recordings of his music and collaborations with different musicians from Europe and the United States. He combined received tapes with his music or sent his tapes to his collaborates who released their home-made cassettes. One of his major successes was releasing of a cassette compilation entitled Third Generation Serious Music with compositions, collected by the concourse.

Living in a small town of Slovenska Bistrica was not a handicap for Mario Marzidovšek. On the contrary. His personal experience (he worked in a chemical factory) was the essential "input" of his creativeness and radicalism. His work was to prove that local and global productions nowadays may not be in contradiction. If anyone wants it, s/he can communicate without limits. The local productions are not necessarily derivations or echoes of the fashionable trends from the centres."

Hope i'll soon have some of his publications that i could share. Meanwhile, i'll post some of his tapes.

Abbildungen Variete - (1983) Abbildungen Varieté [mc,Galerija ŠKUC]

Abbildungen Varieté is the second most important name in Yugoslav/Slovenian oldschool industrial scene of the 80s, besides Laibach. They hailed from Slovenia's second largest city Maribor in the northeasternmost part of Slovenia, then one of the biggest Yugoslav heavy industry centres. Unfortunately, little is known about this project that existed in the short period between 1982-1983 - besides this eponymous cassette-release and the "Novi Rock" compilation contribution with the track "Ishodisce subjekta". The cassete, which is a live-recording, came out in the edition of Ljubljana's ŠKUC label/organisation. What we know about Abbildungen Varieté is that it was close to the NSK [Neue Slowenische Kunst] movement and that Igor Zupe, nowadays a famous slovenian video-artist and a director, was a member. Due to the nature of music, it is highly unlikely that he was the only member and there are also some indications that Mario Ornik of Maribor's KIBLA art group was involved too.

When compared to the rest of industrial scene back then, Abbildungen Varieté was a rare bird and defining them is certainly not an easy task. They had a strong smack of ritual-music, which is also present with Laibach and Strukturne Ptice as an inkling and played a vital role in early Autopsia. So the only bands we can draw paralels to would be from that milleu: Last Few Days, Ain Soph, maybe even Het Zweet. Soundwise it's quite diverse: a bit of sinister tribal drumming with frantic clamor, a bit of solemn ceremonial chanting and a bit of ominous funeral dirges for the banishing of the Dead.

introductory note

this blog will hopefully be an interesting place for all those on lookout for rare 80ies cassette culture gems, experimental music (and film !) aficionados and proto&oldschool industrial listeners. i personally don't have any tapes and wouldn't know how to rip them but am just driven with a feeling of what could be important. also, i'm into categorization & careful listening so that might be helpful.

hope i'll soon change this obnoxiously boring blog title.

welcome everybody :)

21 Most Common Food Service Problems

1. Potentially hazardous foods do not meet temperature requirements.

  • Problem: Perishable food, which consists in whole or in part of eggs, meat, milk, poultry, fish, shellfish or other ingredients capable of supporting rapid bacterial growth, is found at room temperature.
  • Solution: Keep all potentially hazardous food at safe temperature: cold foods 5 C (41 F) or below, hot foods 60 C (140 F) or above.

2. Potentially hazardous foods are not properly thawed.

  • Problem: Meat, poultry and seafood thawed at room temperature. This practice is extremely dangerous. The surface of the food rapidly warms to the danger zone. (5 C to 60 C) and after several hours can produce enough germs or toxin to cause illness.
  • Solution: Plan your menu and thaw frozen foods in the refrigerator. Remember large items such as turkeys may take as long as 72 hours to thaw. In an emergency, frozen potentially hazardous foods may be thawed under running potable water at 21 C (70 F) or below until thawed; then cooked or refrigerated. If food is thawed in a microwave, it must be immediately transferred to a conventional cooking unit as part of a continuous cooking process.

3. Thermometers are not provided or are not conspicuously located.

  • Problem: Thermometers are not available or easily located in refrigeration units and at heating units.
  • Solution: A major safeguard in handling food for the public's consumption is the maintenance of proper temperature. Thermometers must be kept in all refrigerators so that temperatures can be conveniently monitored at all times. For units without built-in thermometers, we recommend that small non-mercury thermometers be taped to the inside of the door, since they are easily lost or broken when placed on racks. Metal stem thermometers must be available for monitoring temperatures of foods in "hot holding". Remember, keep hot foods hot (60 C or above), and cold foods cold (5 C or below).

4. Food protection is inadequate.

  • Problem: Food stored in refrigerators and walk-in coolers is not covered or wrapped. Sacks of potatoes and onions, crates of vegetables and fruits, cases of canned goods, and other food items stored on the floor.
  • Solution: The floor area for such storage cannot be cleaned; dust and debris are swept onto and between these items when the adjoining floor area is cleaned, the dirty bottoms of these food containers contaminate clean surfaces when the containers are lifted onto tables or benches, and the storage area becomes more attractive to the harborage of insect and rodent pests. Install shelving at least 6 inches above the floor. The area beneath the shelving must be accessible for cleaning, or the void sealed with a tight fitting base plate. For items which are too large or bulky for shelf storage, use pallets and keep the area underneath clean. Cover all refrigerated foods. Do not stack food items in the refrigerator.

5. Handling of food is not minimized.

  • Problem: The use of containers without handles (such as bowls, cups, and glasses)
    for scooping flour, sugar and other bulk materials from storage bins which may result in contamination of bulk food items from contact with workers' hands.
  • Solution: Scoops with handles must be provided, as they prevent foodhandlers from running their fingers and hands through the food materials. In many instances, transmission of germs can also be reduced by using forks, knives, tongs, scoops and other utensils that minimize the handling of food.

6. Hygienic practices are not used.

  • Problem: Eating, smoking or use of tobacco in any form while in food preparation, service, equipment or utensil washing areas. Since the hands of smokers come into contact with the mouth each time a cigarette is taken from the mouth, smoking employees may contaminate the product with which they are working with bacteria from their mouth.
  • Solution: No smoking or eating should be permitted in the food preparation area at any time. If smoking is permitted in the storeroom, sufficient ashtrays should be provided and individual smoking must wash his/her hands each time he returns to the food preparation area.

7. Food contact surfaces of equipment and utensils are not clean.

  • Problem: Accumulation of dried food substances on slicers, mixers, sugar bins, meat tenderizers, can opener blades, refrigerator shelves and door handles, and other equipment that normally comes into contact with food products.
  • Solution: Clean and sanitize meat slicers and cutting boards between uses or different types of food, such as meat and vegetables, to avoid "cross-contamination". Clean all kitchen equipment on a regular schedule.

8. Non-food contact surfaces of equipment and utensils are not clean.

  • Problem: Unclean counters, shelves, insides and tops of refrigerators, ovens, tables, tops of mixers and exteriors of exhaust hoods. These surfaces must be kept clean so dirt does not fall into food containers or attract insects.
  • Solution: Utilize a cleaning checklist to insure periodic cleaning of all non-food contact surfaces.

9. Dishwashing facilities are inadequate.

  • Problem: Manual dishwashing - improper sequence in three compartment sink.
  • Solution: Wash all utensils in hot water containing detergent, rinse in hot clean water and sanitize in the third compartment by immersing in water containing approved sanitizer for one minute.
  • Problem: Dishwash machine - improper maintenance of machine, including broken temperature gauges, clogged rinse jets, and heavy lime build-ups.
  • Solution: Check dishwash machine daily for proper cleaning and maintenance. Keep several spare parts on hand.

10. Sanitation rinse is not used.

Adequate dishwashing is one of the most important procedures in the food service operation in breaking the chain of infection from customer to customer.

  • Problem: Manual dishwashing - no test kit available to periodically check the concentration of the sanitizing chemical.
  • Solution: Obtain address of test kit from your Sanitarian.
  • Problem: Dishwash machines - machines using hot water for final rinse not reaching the required 82 C (180 F), or lack of bleach in machines designed to dispense chlorine with final rinse.
  • Solution: Check the dishwash final rinse daily to insure it reaches the required gauge temperature of 82 C (180 F) final rinse, or check the chlorine dispenser reservoir daily.

11. Original containers are not used, or container is not properly labeled.

  • Problem: Foods received in large or bulky containers are transferred to smaller but unlabeled containers. Sometimes the small can of salt or sugar kept handy to the stove gets confused with the rat or roach poison kept in an identical can.
  • Solution: Unless the food item is easily identifiable and cannot be mistaken for another product, store it in clearly labeled containers. Keep all poisons and other toxic materials sorted in their original container and in a safe place (segregate complete from food storage). Do not store cleaning compounds in the same cabinet as insecticides and rodenticides. Use only smooth, easily cleanable containers for food; empty tin cans do not meet this requirement.

12. Storage of clean equipment and utensils is not appropriate.

  • Problem: Cups and glasses stored on toweling. Pans stored before thoroughly dry, and in some cases "clean" pots and pans stored on floor.
  • Solution: Store cups and glasses on rubber matting to allow air circulation and invert dry pots and pans on storage racks.

13. Food- or ice-dispensing utensils are improperly stored.

  • Problem: Ice cream dipper is stored in milk shake container half full of water. Handle of ice scoop is covered with ice.
  • Solution: Store ice cream scoop in cold running water, or clean and dry after each use. Store ice scoop with handle up or in a clean, protected place near the ice machine.

14. Single service articles are not stored properly or do not have proper dispensers.

  • Problem: No dispenser for single service cups or such articles handled or dispensed in a matter that contaminate surfaces which may come into contact with food or the mouth of the user.
  • Solution: Use dispensers and insure single service articles are used only once. Store single service articles in covered cartons or containers which protect them from contamination.

15. Cross connections cause back siphonage or backflow.

  • Problem: Rubber hoses directly attached to kitchen sink or janitor's mop sink. Variations in water pressure can cause a vacuum in the water lines. If hoses are reaching into the sink, dishwater or mopwater can be drawn back into the public water supply.
  • Solution: Install vacuum breakers on all spigots with hoses or place vacuum breaker on hose bib.

16. Toilet and handwashing facilities are not proper or adequate.

  • Problem: Toilet facilities not clean and in good repair; single service towels and soap not provided at handwash sinks.
  • Solution: Clean and properly maintained toilet facilities generate a proper attitude toward sanitary practices and conditions in the food service establishment. It is extremely important that employees wash their hands after using the toilet facilities and after handling contaminated materials in the kitchen in order to break the chain of infection.

17. Indoor and outdoor storage is not properly maintained.

  • Problem: Garbage cans are not kept clean, or covered with tight fitting lids; dumpsters are dirty and lids are left open.
  • Solution: Clean garbage cans after each use and cover when not in continuous use; keep dumpster lids closed and dispose with sufficient frequency to prevent a nuisance.

18. Construction of floors, walls and ceilings does not meet specifications.

  • Problem:: Broken tile or linoleum flooring; dirty and greasy walls and un-cleanable ceilings.
  • Solution: Maintain floor in food preparation and storage areas to be smooth, nonabsorbent and easily cleanable; keep wall and ceiling clean and in good repair.

19. Lighting is not provided as required and fixtures are not shielded.

  • Problem: Inadequate lighting on food preparation and dishwashing areas; no shields on kitchen lights.
  • Solution: Provide at least 538 lux (50 foot candles of light) on all working surfaces and at least 323 lux (30 foot candles of light) to all other surfaces and equipment in food preparation, utensil washing and hand washing areas; shield light fixtures in food preparation and service areas to protect against broken glass falling into food.

20. Wiping cloths are not clean or use-restricted.

  • Problem: Wiping cloth on counter, used to wipe spill on floor.
  • Solution: Wiping cloth or dishrags used for wiping food spills must be used for no other purpose, and should be frequently rinsed in an approved sanitizing solution.

21. Food preparation surface is uncleanable.

  • Problem: Plywood and other soft woods may not be used for cutting boards, sandwich preparation tables, or other food contact surfaces as they cannot be kept in a sanitary condition. Hard maple, which is the only wood approved for such use, that has cracks or scoring which make the surface unsanitizeable.
  • Solution: Use only hard maple or plastic for cutting boards, sandwich tables, and other food contact surfaces. When maple becomes cracked, discard it. Deep scoring of maple must be removed by refinishing, or the board discarded
