On May 20th Black Label Society performed at the House Of Blues in Chicago, IL. They were joined at one point by vocalist Phil Anselmo for a cover of the Pantera classic "I'm Broken". Fan-filmed video is available below:

While former Pantera vocalist Anselmo doesn't seem too up for the idea of commemorating the ten year anniversary of Dimebag Darrell's death with Black Label Society's Zakk Wylde standing in for Dime in a special reunion, he said he's open to working with Zakk to honor the guitarist's life.

In a recent interview with Artisan News he said: "Sure, if we wanted to write an homage to Dimebag together, that would be one thing, and I'd definitely be up for that. But not for his death. I'd prefer to write a song that celebrated his life."

Simon & Schuster's Gallery Books will release Phil Anselmo's autobiography, Mouth For War: Pantera And Beyond, on January 13th, 2015.

In this brutally honest, no-holds-barred memoir, Philip Anselmo, former frontman of the legendary metal band Pantera, finally tells his side of the story - on everything from the band’s meteoric rise to the murder of guitarist Darrell Abbott onstage.

From bar band obscurity to the bright spotlight of the world’s stage, Anselmo helped lead Pantera to world domination. He soared to the top with the first extreme metal album to debut at #1 on the Billboard music charts with Far Beyond Driven in 1994. He turned a bar-bumping glam metal band into the heaviest, most extreme, and most successful heavy metal unit since Metallica. But the ride to the top wasn’t easy.

Soon after Far Beyond Driven topped the charts, Anselmo hit rock bottom at the band’s celebrated return gig in Dallas, Texas, where he was declared clinically dead for more than four minutes after he overdosed on heroin. He later watched Pantera disintegrate due to backbiting, alcohol and drug abuse, and chronic pain. And in addition to nearly killing himself, Anselmo has been blamed for killing the band and wrongfully accused as the reason his best friend and guitarist “Dimebag” Darrell Abbott was murdered onstage by a deranged fan.

Anselmo’s rise to the top of the heavy metal heap as the ultimate frontman is the stuff of modern-day legend. Finally, he tells all in this fascinating narrative of his hard-won music career with incredible highs and devastating lows. Mouth For War is the hard, honest, brutal truth.
