Straight Life by Art Pepper, Raise up off me by Hampton Hawes. Both "warts and all" autobiographies which address addiction issues. Don't know about e-book availability.
The Monk biography by Kelley is excellent. Isoardi's bio of Horace Tapscott, The Dark Tree - if you can find it.
I enjoyed John Szwed's biography of Sun Ra, Space is the Place. Szwed's work impressed me, and I expect any of his writing on subjects of interest would be worthwhile.
