Breaking news from the legendary thrash metallers of Anthrax. Lead guitarist Rob Caggiano has left the band to focus on production work.

Having joined Anthrax in 2001, Caggiano stuck with the New York thrash band until the group's 'Among the Living' lineup reunited in 2005. However, Caggiano was brought back in 2007, remaining as Anthrax's lead guitarist until now.

The announcement comes as a big surprise, as Anthrax have been experiencing their greatest success in years on the heels of their critically acclaimed 2011 album, 'Worship Music,' which just yielded a Grammy nomination for the track 'I'm Alive.'

Caggiano explains his departure in statement just released by the guitarist himself:

I'm extremely proud of my time in Anthrax. Actually, that's an understatement! We accomplished so many great things together over the years and I shared some of the best times of my life with these guys. As a band, we also weathered quite a few storms along the way. It's been a wild ride (to say the least) from Day One and I wouldn't change one single thing about the last 12 years. This is an extremely difficult and emotional decision for me to make but my heart is just steering me in a different direction right now. I've always been one to follow my heart in everything that I do and while this might be one of the hardest decisions I have ever had to make, it feels like the right one for me at this time. Scott, Charlie, Joey, Frankie (and John Bush) will always be part of my family and this decision doesn't change the way I feel about that in the slightest. I would also like to say thanks to all the amazing fans I've met and hung out with worldwide over the years. You guys always were and always will be the reason why I make music! In this day and age, being a musician isn't always easy -also an understatement- but the fans truly make it worthwhile for me. I hope to see each and every one of you again really soon. The fact that Anthrax is at the top of their game right now and totally 'out for blood' after all these years is a testament to this band's longevity and conviction! I'm truly honored to have been a part of their brilliant legacy.

As for this future, the former Anthrax shredder will continue his career as an in-studio producer:

I can't wait to get back in the recording studio again! Over the years, I've been blessed with the privilege of working with a wide range of great bands/artists from Anthrax and Cradle of Filth all the way to Bruce Springsteen, and I look forward to a hopeful continuation of that side of my career while I figure out my next move as an artist. BTW in case anyone was wondering after reading all of this, I do FULLY intend to get back out there on the road very soon in some way shape or form....it's in my blood!

Anthrax have also released their own statement, wishing their friend the best on his new path:

Rob has been an integral part of Anthrax for so many years, as our lead guitarist, in a production capacity, but most of all, as our close friend.  His contributions to the band have been enormous. While we are sad that he is leaving, we wish him nothing but great success going forward, and hope to share the stage with him again sometime down the road.

With the Metal Alliance Tour on the horizon, we have been considering several lead guitarist options, and will be making an announcement on that shortly.

Stay tuned for Anthrax's decision on who will replace Caggiano on lead guitar for the 2013 Metal Alliance tour, along with Caggiano's future plans as a producer.
