TOOL's MAYNARD JAMES KEENAN Discusses Upcoming Authorized Biography

TOOL frontman Maynard James Keenan's biography will be published in the fall of 2016 via Backbeat Books. The book will be written by Sarah Jensen and is authorized by Keenan, who will collaborate with Jensen on the book.

Speaking to RollingStone.com about how the idea for his biography came about, Keenan said: "One of my best friends in high school, we're still close, his sister's a writer, she's 10 years older than we are; she's kind of been around for a while, of course, seeing everything that went on pre–high school, high school, etc. So I approached her, because she's a writer, to see if she was interested in helping me work on a semi-autobiography. Because I didn't really want to write it as an autobiography, first-person — I'd rather have it be more in story form, like you're kind of along for the journey, with sidebars by me throughout, in my voice, kind of expanding on particular instances or anecdotes. But for the most part, it's just she and I on the phone a couple times a week, just going over timelines, going over stories, etc."

Asked if he is giving Jensen license to incorporate all the information as she sees fit, Keenan said: "She'll write section-by-section; we'll go back and edit and fix and tweak, section-by-section, chapter-by-chapter. We have conversations twice a week to just go over... She'll send me the chapters, and I'll read them through, and then she'll have questions or clarifications, contradictions. You talk to somebody else; they didn't remember it the same way, so you had to rack your brain and go, 'Okay, was I drunk? Did I sleep through that?' A lot of just editing, fact-checking. But we're pretty much ... For the most part, it's not complete, but it's 90 percent complete, so we're hoping to have it out by fall, next fall."

Keenan's other band, PUSCIFER, will release its third studio album, "Money Shot", on October 30.

A six-week tour in support of the record will kick off on November 1 at the Monster Mash festival in Phoenix, winding down on December 12 in Las Vegas.

TOOL will also appear at the Monster Mash event, but will play the day before on October 31.

TOOL guitarist Adam Jones revealed in March that the band had finally settled a complicated lawsuit that had dragged on for eight years, setting back the band's recording plans. The group is now reportedly working at a faster pace on music for its first new studio set since 2006.
