Andre Sider af Sonic Youth presents the complete Other Sides of Sonic Youth improvised live performance from the 2005 Roskilde Festival in Denmark, featuring Sonic Youth (with Jim O'Rourke) and guests Swedish saxophonist Mats Gustafsson and Japanese sound artist Masami Akita (a.k.a. Merzbow). The single piece performed was a structured improvisation which for 60 minutes added and subtracted musicians one by one until only Akita was left onstage. This installment of Sonic Youth's series of experimental and mostly instrumental releases is available in a CD-only edition on the band's own SYR label.
