<DIV>Derek Bailey&#8217;s <I>Improvisation</I>, originally published in 1980, and here updated and extended with new interviews and photographs, is the first book to deal with the nature of improvisation in all its forms&#8212;Indian music, flamenco, baroque, organ music, rock, jazz, contemporary, and &#8221;free&#8221; music. By drawing on conversations with some of today&#8217;s seminal improvisers&#8212;including John Zorn, Jerry Garcia, Steve Howe, Steve Lacy, Lionel Salter, Earle Brown, Paco Pe&#241;a, Max Roach, Evan Parker, and Ronnie Scott&#8212;Bailey offers a clear-eyed view of the breathtaking spectrum of possibilities inherent in improvisational practice, while underpinning its importance as the basis for all music-making.</Div>
