7Ai9is a compilation of old cassette demos from the beginning of 80's plus few new tracks.
All the trracks are very exclusive and absurdly random. Piitu Lintunen is a Finnish 80-90-2000-influencer and record collector. In early 80s he made a punk zine called Pöly with his brother. He was actively in contact with industrial artists like Merzbow and Genesis P Orridge. Many of these compilation tracks are from demo tapes from that time.
