Mark, I think it's generally a pretty good bio as well. I wrote a review of it when it came out for our local alterna-weekly and praised it for the most part, but I did get annoyed by Santoro's style at times; "Mingus was feeling the zeitgeist" was one refrain that got on my nerves. Santoro came across my review online and actually sent my editor a thank-you note, which surprised me, since I did make some pretty incisive remarks about his writing manner... but I found it a more lively read than Brian Priestly's rather pedestrian treatment (IMO), although I know many prefer it to Santoro's book.
