The last two years have been a hellish ride for Chimaira. First, they lost three band members -- drummer Andols Herrick, bassist Jim Lamarca and keyboardist Chris Spicuzza. After a brief period of panicking, they replaced the dudes with two members of Daath, multi-instrumentalist Emil Werstler on bass and keyboardist Sean Zatorsky. Then they added drummer Austin D'Amond and wrote one of their  best albums to date, 'The Age of Hell.' But now, Hell hath unleashed its unpredictable fury yet again.

Frontman Mark Hunter has just announced that lead guitarist Rob Arnold and rhythm guitarist Matt DeVries will be leaving Chimaira at the end of 2011. "Of course this was a huge blow, but there were no hard feelings," said Hunter on the band's official site, adding that the two announced their decision to leave in July. "We understand that life invades art, everything runs its course, and we have to take different paths. We respect their decision and wish them only the best. We made heavy metal history together and that is all that matters at the end of the day."

Arnold and DeVries will play their last show with Chimaira at the Chimaira Christmas 12 show on Dec. 30 at the House of Blues in Cleveland, Ohio. At this point, Hunter has not announced whether or not he plans to rebuild Chimaira in 2012.
