Having read the book cover to cover now I must agree that it's a bit of a mixed bag - some very interesting sections covering the likes of Joseph Holbrooke Trio, AMM, Neil Ardley/NJO, Mike Osborne, Graham Collier & Mike Westbrook but far too much inter-linking with Marxist theory to spin a (very debatable and somewhat biased) narrative. The section on drugs/alchohol was quite interesting - hadn't heard of that Bert Courtley chlorodyne story. The musical 'critique' is also good - can't disagree with many of the choices re: key recordings. Some artists mentioned briefly in passing deserve much more prominence though - Dick Morrissey, Amancio D'Silva and Ronnie Ross come to mind. Having said that - people such as Ray Russell, Mike Taylor and Howard Riley get the prominent mentions they deserve. Nice to see John Dankworth's 60s big band writing given prominence too.
There's really two books here - with a very good one covering British Jazz developments 1960-75 trying to get out. I found the sloppy editing/proofing in parts very annoying too. Kudos though that this book was written in the first place - the author's considerable knowledge of and enthusiasm for the music wins through.
