John Chilton's Who's Who of Jazz has established itself as a major jazz reference book on the lives of over a thousand musicians born before 1920. The informative biographies give the essential details of each musician's life and career, and jazz greats jostle with unknowns for the readers attention. This completely revised edition adds much new information to the musical histories of the players, and the biographies of some of the major figures have been rewritten to incorporate recent research.
