I've read many books profiling musicians. One of my favorites is
Every Night's a Saturday Night: The Rock 'n' Roll Life of Legendary Sax Man Bobby Keys
It's an unbelievable story. Bobby is like the Forest Gump of rock n roll. Bobby tells his story as if you sat down next to him on a bar stool. His encounters with Buddy Holly, King Curtis, Elvis, Mick Jagger, John Lennon, etc. are as honest as they are amazing.
