This post should make many of you happy. It is the highly sought-after RNA Organism LP released on Vanity Records in 1980. An unexpected snowfall kept me indoors most of the day allowing me to archive this fine album.
Again, to quote the Vanity Records label article in Music Magazine:
"Receiving a cassette tape from RNA Organism by air-mail, Agi (Yuzuru - head of Vanity Records) mistakenly thought they were from overseas and highly acclaimed the band in Rock Magazine, however, it was a clever ploy by Kaoru Sato from Kyoto. This album is amazing dub music with funky bass, noise guitar, trumpet and rhythm machine - sort of like a heavier version of Andy Partridge's Take Away. Subsequently the group changed its name to EP-4, which became known for its guerrilla live performances as well as simultaneously releasing its debut album from both major and indie labels. Meanwhile, Sato disappeared from the music scene in the mid-80's."
A Japanese music source on-line provides a little detail regarding one of their performances from 1983 - what looks to be three appearances around Japan in one day:
"The most remarkable thing about them is 1983.5.21 incident. The name care sized seal of +----+ was attached on electric-light poles, 5.21 billboard, walls of building, telephone booths and everywhere in Harajyuku and Shibuya (in Tokyo). On the day of event, they performed gigs with time lag at 12:00 in Osaka, at 18:00 in Nagoya, at 1:00 at night in +----+ (originally at 0:00), at 4:30 in Tokyo. The seal became a sort of social phenomenon. Despite mid-night gigs, many stylish and snobbish people gathered in Shibuya. At the same time, it was the day that they were supposed to released LP's (Multilevel Holarchy: Indies, Showa Demise: Major); however, "Showa Demise" infringed the regulation of record and Multi Label Horror Key was released only. Later, it was renamed as "Showa Amnesty and released as book with LP-sized thin small magazine from Indie."
Aside from the RNA Organism LP, Sato released seven albums that I know of as EP-4 stretching into the 90's (not disappearing in the 80's per the Music article):
Seifuku Nikutai 
Multilevel Holarchy 
Lingua Franca 1 
The Crystal Monster 
Five To One [Hot Records (Australia), 1985]
Lingua Franca X 
Found Tapes 
Aside from sounding similar to other Japanese New Wave/No Wave/Electronic artists at the time, there is also a strong bond here with the early 80's German New Wave/Electronic scene. Truly one of the best records from the early 80's.
