Each person makes a mixtape and sends it to the organiser (that used to be Pookie, but now its Danny Himself). Then the organiser redistributes them randomly.

Its very good fun, and there's a mixtape round 6 up somewhere at the moment.

According to his website, 'Approaching Silence' accompanied the multi media work 'Redemption' installed at the P3 Gallery, Tokyo 1994. The CD was compiled and released in 1999..

The whole thing says: This album contains three compositions (two of them long form) created exclusively for two independent gallery installations. Two pieces,'The Beekeepers Apprentice' and 'Epiphany' originally accompanied the 'Ember Glance' installation, a multi media work made in collaboration with the artists Russell Mills and Ian Walton, and exhibited in Tokyo, September 1990. 'Approaching Silence' accompanied the multi media work 'Redemption' installed at the P3 Gallery, Tokyo 1994. The CD was compiled and released in 1999.

I found a link for the P3 gallery on this page, but it doesn't work.

There's some more information on the cd sleeve:

Redemption - Approaching Silence: a multi-media installation by David Sylvian and Robert Fripp with Haruki Kaito and Adam Lowe staged at P3 Art and Environment, Tochoji Zen Temple, Shinjuku-Ku, Tokyo, August 30 - October 12, 1994.

Excellent! It's nice to see the work itself. Thank you.
