Book excerpt: Bix Beiderbecke, born in 1903 and dead at 28, lives on as perhaps the greatest cornetists in jazz history. The author, a teenage fan of Bix and the younger brother of Vic Berton, Bix's drummer and manager, offers his unique perspective of the music as he tagged along with the band to honky-tonks and jam sessions. Listening from under the piano, Berton heard some of the most extraordinary music, and he brings it alive in this book, which combines the excitement of youth and the perspective of the five decades that followed - decades that confirmed Bix's place in the pantheon of jazz greats.
