Here's five I've enjoyed that I haven't noticed anyone mention yet.
Jack Bruce- Composing Himself
Not sure how many fans of Jack Bruce's solo work are hanging out here, but I've enjoyed my share and I enjoyed this very thorough bio that ranges from his school years on a classical music scholarship through the 'Quest for Smack' years touring with West, Bruce, and Lang, and on through many diverse collaborations in his later years. So there's a definite 'don't meet your heros' factor here, but there's also a panoramic spread of a musical life where Bruce generally sought artistic growth over commercial success, collaborated with jazz and world music icons, bought an island... it's not a dull life. And it's amazing that he lived as long as he did.
White Bicycles- Joe Boyd
The prose is a little overblown but the man was present and participating at a ridiculous number of pop music milestones, from running the PA at Newport when Dylan went electric to signing and producing most of the originators of folk-rock in the UK including Fairport Convention, John Martyn, Nick Drake, Richard & Linda Thompson, etc. There's more, but until I get my copy back from whoever I lent it to more details will have to wait.
Glyn Johns- Sound Man
Speaking of producers, Johns produced.... so many classic albums. The Rolling Stones, Eric Clapton, the Eagles, the Who, the Clash, even one by Fairport Convention. Decent writer too, and entertaining company as he shares stories from his career and life.
Complicated Games- Inside the Songs of XTC
Pretty much what the title says, Todd Berhnardt interviewing Andy Partridge, each chapter devoted to a particular song in the XTC/Dukes of the Stratosphear discography. Those of us who've recently delved into XTC through the Wilson remixes will find much of interest as you evesdrop on the cool kids discussing how the sausage was made.
Roger Daltrey- Thanks a Lot Mr Kibblewhite: My Story
Nicely done autobiography, easy on the tawdry stuff and a little easy on himself sometimes but mostly reads as an honest look back with much gratitude expressed; I wasn't expecting to like him more by the end but he spun a good yarn.
