Hooch, agree about Christgau. His collected reviews from the 1970s and 1980s influenced my buying habits for a long time. The Ehs and Eh pluses steered me right most of the time.
I recently saw a documentary on Lillian Roxon. Obviously didn't know much about her except that I had her Encyclopedia of Rock from 1969/71. Had to check the introduction just to prove to myself that there was no mention that she was from Australia. News to me from the doc. I wish some of her writings from the late 1960s/early 70s could be collected.
Also agree about the Mingus book. Haven't read that in a while. Picked up a book done by Sue Graham Mingus, Tonight at Noon, which will be read some day.
Another jazz book of interest is Artie Shaw's The Trouble With Cinderella.
Joe Carducci's Rock and the Pop Narcotic. Bob Greene's Billion Dollar Babies. Some old Vintage Press books like The Age of Rock and Twenty Minute Fandangos and Forever Changes. Scholastic book titles. The list goes on.
