Do yourself a favour and read
Electric Don Quixote by Neil Slaven. That will give you a better, more balanced idea of Zappa (and probably more accurate) than any other single book.
The Miles biography is as skewed to one side as
The Real Frank Zappa autobiography is to the other. Nothing really new other than some of the author's own conclusions that draw a bit too heavily from Zappa's public persona.
Still, no-one can deny that Zappa was a genius (in many areas), and that he did have flaws - just not necessarily the ones Miles says he has.?
