Jim O'Rourke
He was long associated with the Chicago experimental and improv scene.
Composer/improviser/producer Jim O'Rourke has recorded as a member of the experimental rock groups Gastr Del Sol, The Red Krayola, Brise Glace and Yona Kit, recorded a number of his own albums of pop rock, guitar improvisation and musique-concrète compositions on the Drag City, Staalplaat, Extreme, Divided, Entenpfuhl and Metamkine labels, released collaborative recordings with Henry Kaiser, K.K. Null, Gunter Muller, Eddie Prevost, Evan Parker, Phill Niblock and Mats Gustafsson, and produced albums by Tony Conrad, Faust, Melt Banana and Space Streakings. Until recently O'Rourke was most active as a producer and member of Sonic Youth, but he left the band in late 2005. He has since issued some of his more experimental early pieces such as "6 Oscillators '87 / Guitar '88", and contributed to projects such as Diskaholics Anonymous Trio, among others.
