Slightly a side track - two superb biographical books about two archetypal glam rockers:
Nikki Sixx' The Heroin Diaries was just amazing. Hilarious, dramatic, heartrending. honest, intelligent and really literate description of the road down into a drug-soaked, lonely hell. And you don't just get to hear Nikki's voice, but also those of the people he mentions in his diary notes, who were around the place: bandmates, musicians, friends, producers, women around the band: he bravely invited them to write their own comment posts to specific days and incidents twenty years after. Plus THD has some of the greatest integration of text and pictures I've ever seen in a book on music.
And George Tremlett's Bowie: Living on the Brink does some of the same for David Bowie's career (the seventies especially). The guy is insightful, he understands both Bowie's creative side, his love of theatre and the business side of rock music - Bowie's struggle for breakthrough and then for the rights to his own music and control of the millions he generates, and against drugs and alcohol. Lots of wonderful anecdotes about the zany side of touring and recording with Bowie, too. Tremlett didn't do any new interviews with Bowie when he wrote his book in the mid-nineties but he'd had long talks with him at his home a couple times around 1970 and knows most of the key people in Bowie's early career, whom he interviewed again for the book (excepting Angie Bowie - he knew her at the time she was Mrs.Bowie but I don't think he talked to her again).
