Thom Brennan. Seems to have disappeared from the earth (along with Tetsu Inoue). No new album for five or so years.
Andrey Faryus (Faria Records). I assume the label folded, but never heard anything for years.
Patrick O Hearn. Seems ages ago there was new music.
Steve Roach. No new album in about three months. I'm starting to worry.
