Why have you given up on bios?
In general, I find too much emphasis on the unhappy or negative in music bios. I hear a lot in the music that I don't read much about in the biographies.
The last musician's bio I read was Kelley's Thelonious Monk. After reading it, I felt depressed. Perhaps all of the details that Kelley reports occured, but there must have been a lot more than those details, because I hear Monk's music very differently than what I experienced in reading that book.
All of this leads to a discussion of how much of musicians' lives go into their music, and how do life experiences find their way into the music. I don't have enough lifetime left to go there. I'd rather just listen.
I guess what I want to say is listening to the music brings me far closer than any biography could ever hope to.
