I played a recording I did with C. Spencer Yeh, back from November 2009. Solo violin piece clocking in ~30 minutes, followed by a sick solo voice piece. Sounds as excellent in 2012 as it did the day he played it. Sweet.

The bulk of this show was dedicated to the works of the Sonic Arts Union, a collective of experimental music artists active between 1966-76. Members were Alvin Lucier, David Behrman, Gordon Mumma, and Robert Ashley.
