Apparently there will be much in 2013 to change. This is the second announcement this week of seperation from a major band. This one involves Anthrax.
I found this comment on the Rock Over America Magazine Facebook page.
Statement from Anthrax about Rob Caggiano's Departure From the Band:
January 4, 2013
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.
We here at ROA will be looking forward to more announcements.
