Martin (philosophy, DePaul U.) explores the roots of avant-garde rock music, which evolved out of the cultural and political turmoil of the 1960s. He discusses both the pioneers of the movement and contemporary figures, analyzing numerous artists and groups and offering commentary on the esthetic and socio-political issues raised by the development of this form. He traces the phenomenon of its rise from Yoko Ono and Velvet Underground through progressive and punk rock in the 1970s to current artists such as Sonic Youth, Stereolab, and others. He also provides discographies. Annotation c. Book News, Inc., Portland, OR (booknews.com)
