Richard Cook's Jazz Encyclopedia is not merely an A-Z guide to the artists and bands who have shaped jazz, but it also tracks the history of jazz and its changing styles. This is a wonderfully accessible work. Richard Cook's passion for jazz and his strongly held opinions make this the liveliest and most trenchantly witty encyclopedia you'll have read. Whether you're trying to find out why Louis Armstrong was called Satchmo (his nickname as a kid was Satchelmouth), what bebop is, or the difference between Gil Evans and Bill Evans - this book has all the answers.
