I would assume it was active in late 80's, as label put out also compilation stuff, including Japanese artists of that era. I doubt label was widely acknowledged or "popular". It did not seem to be so much part of Japanese noise, as it was so much based on UK PE worship & copycat methods. At most obvious when including things like playing Whitehouse LP with added own vocals, hah..
Most of these tapes are quite fun and clumsy. Very over the top, amusing japanese-english kind of track titles with german terms thrown in.
Whether guy was bootlegger of euro PE releases and blatant copycat with pretty much zero personal input, I do have the soft spot for this level of ridiculousness. Imperial Japan, UK PE worship, WWII german incidents and a bit of scatology and anal obsession thrown together. Can't be *that* bad, haha..
