Video footage of ANTHRAX drummer Charlie Benante "working on some drum fills" can be seen below.ANTHRAX has seven songs arranged musically for the band's next studio album, which is expected to arrive sometime in 2014. The band's guitarist, Scott Ian previously described ANTHRAX's new material as "aggressive, fast, even riffier than the last record and some of it is difficult to play. Nothing like writing parts that are above my ability as a guitar player! When that happens, the drill sergeant in my brain yells, 'PRACTICE, YOU LAZY FUCK!' So I do. And I nail that shit." Benante recently spent time recovering from surgery for carpal tunnel syndrome. He rejoined his bandmates for their September 13 performance at "The Battle Of San Bernardino" festival in San Bernardino, California alongside IRON MAIDEN, MEGADETH, TESTAMENT, OVERKILL and SABATON. Guitarist Jon Donais (SHADOWS FALL) has been touring with ANTHRAX since Rob Caggiano's departure in January, and will continue to play with ANTHRAX for the foreseeable future. ANTHRAX's latest studio album, "Worship Music", has sold more than 100,000 copies in the United States since its September 2011 release.
