Aerosmith Says Book Tells All

September 2 [16:00 EDT] -- Advance copies of the official authorized Aerosmith biography, "Walk This Way," are circulating to mixed reviews.

The book, due out in hardcover by Avon books in October, was written by the band with co-author Stephen Davis, who penned the Led Zeppelin history, "Hammer of the Gods," a Fleetwood Mac bio and others.

According to the press release, the tome chronicles a quarter-century in the quintet's career, including reportedly candid glimpses of the life, music, legends, lost weeks, raunchy unsafe sex and mountains of drugs. Said guitarist Perry: "I mean, we're not talking schizophrenia here. Just self-destruction with a sense of humor."

The release promises that the book is "not some whitewashed, overblown hype penned by some fawning fanzine journalist or a one-sided expose spewed out by a pissed-off one-time insider. 'Walk This Way'," it says, "is the real thing--an almost day-by-day account of the high-and-low life of a true rock 'n'

roll monster in the words of the guys who made it happen."

It's unlikely that it's any more sensational than "Dream On: Livin' on the Edge with Steven Tyler and Aerosmith," a book put out last year around this time by Steven Tyler's ex-wife Cyrinda Foxe.
