Yes, I finally picked up a copy of Japrocksampler. If you haven't read it before, I highly recommend buying the book. I'll probably be posting quite a few albums from Julian Cope's top 50, but I'm going to start with this one, since I've been listening to it a lot lately.
The album is Amalgamation by Masahiko Satoh and the Soundbreakers. Satoh is a jazz pianist. This album, which was one of the many "super sessions" which were created during this time period, featured many other musicians such as Kimio Mizutani, who was already known for his guitar work with the group Love Live Life + One.
This album is a bit difficult to describe. It is a mixture of psychedelic music, musique concrete, progressive rock and free jazz. The record is quite unpredictable, and features a lot of unique instrumentation, including some traditional Japanese instruments. Listening to it is a pretty strange trip.
The record is seperated into 2 tracks, side one and side two. Side one is 15 minutes and 49 seconds long. Side two is 21 minutes and 18 seconds.
