Of those not mentioned I liked Andy Summers's memoir (some prog content), Edward Macan's book about ELP and Yesstories by Tim Morse.
There was a book in the early 90's by a writer named Cole Gagne titled Sonic Transports about Fred Frith and the Residents, as well as Glenn Branca and Blue Gene Tyranny (two artists I haven't followed as much). Don't know how easy it is to find now.
