Legendary experimental guitarist Fred Frith performs improvisations at the 11th Other Minds Music Festival at San Francisco's Yerba Buena Center for the Arts, 2005. Frith performed at the festival both as a soloist and as a member of the due Normal, alongside Sudhu Tewari, a Bay Area resident of Indian descent whose remarkable music is performed on homemade acoustic instruments. Since recording Guitar Solos in 1974, Frith has been regarded as one of a handful of radical innovators on the instrument. He has collaborated with such luminaries as guitarist Derek Bailey, Bill Laswell, Miya Masaoka, Hans Reichel, Heiner Goebbels, John Zorn, Han Bennick, and Christian Marclay. A co-founder of the English rock group Henry Cow, Frith also has composed a significant body of chamber music for such groups as the ASKO Ensemble, Rova Saxophone Quartet, and Ensemble Modern.
