"James Hetfield: The Wolf At Metallica's Door", the unauthorized biography of METALLICA's iconic frontman, is scheduled for release on April 22 via Independent Music Press. Penned by Scottish author and journalist Mark Eglinton, the book features interviews with key figures from Hetfield's past, telling insight into the gritty upbringing that moulded the man he would later become.

A description of the book reads as follows: "While the METALLICA story and that of Hetfield are closely linked, this honest and definitive biography focuses exclusively on the man himself, and successfully humanizes and demystifies one of metal's most guarded individuals. Not just that, some of Hetfield's childhood friends from his days growing up in Downey, California have agreed to talk for the first time about their relationship with him; a feature which truly sets this book apart from all related titles to date. Additionally, there is vital input from metal peers such as Charlie Benante [ANTHRAX], Jerry Cantrell [ALICE IN CHAINS], Rex Brown [PANTERA, DOWN], Jeff Waters [ANNIHILATOR] and Mille Petrozza [KREATOR], among a list of equally important others, and to kick things off there's an excellent and fitting foreword by legendary [TESTAMENT] singer Chuck Billy.

"A sad fact worth mentioning too is that both of James Hetfield's parents succumbed to cancer, and as a gesture of recognition, the U.K. publisher IMP is donating 25p of every copy sold to the Cancer Research charity."

"James Hetfield: The Wolf At Metallica's Door" is described as "essential reading for both fans of the man, or indeed anyone receptive to a genuinely inspiring human story."

The Pulse of Radio reports that LINKIN PARK has filed a lawsuit against the Lloyd's of London insurance company, alleging that the firm refused to compensate the band for a string of six shows it canceled after frontmanChester Bennington hurt his back. According to TMZ.com, the group was forced to pull out of six shows in 2008 after Bennington suffered his injury while assembling a toy for his son. But their request to claim the lost profits from the show through Lloyd's was denied by the insurance giant, which alleged that Bennington's problem was pre-existing before LINKIN PARKtook out its policy.

Details of the suit were not available, but LINKIN PARK is said to be suing for millions of dollars.

Bennington has had to pull out of shows in the past due to throat ailments and once because he needed stomach surgery. He admitted to us that drama is often a big part of his life. "For some reason, I feel comfortable being in uncomfortable situation(s)," he said. "I don't like it, I don't like being tormented, so to speak, but for some reason, I'm drawn to — I feel more comfortable as a person being in chaos or being in a crappy situation because I'm used to that. Ever since I was really young, it's always been chaotic and always been crazy, there's always some kind of drama, and so I've just become accustomed to that."

Bennington's side project, DEAD BY SUNRISE, issued its debut album last fall.
