The Japanese contemporary art exhibition was called "Facts Of Life" and was actually as long ago as 2001 (that's memory for you!). The composer who set up this gallery based improv was called Makoto Namura. Loved his vibe.
Talking of which I am still really enjoying the improvs on your MySpace pages. Shame you aren't a bit nearer west London. We could do with a few more people around here doing what you are doing.
