This brilliant biography of the cult guitar player will likely cause you to abandon everything you thought you knew about jazz improvisation, post-punk and the avant-garde. Derek Bailey was at the top of his profession as a dance band and recordsession guitarist when, in the early 1960s, he began playing an uncompromisingly abstract form of music. Today his anti-idiom of "Free Improvisation" has become the lingua franca of the "avant" scene, with Pat Metheny, John Zorn, David Sylvian and Sonic Youths Thurston Moore among his admirers.
