Anthrax drummer Charlie Benante made it official that thrash veterans have kicked off the demoing process for the new album, a follow-up to 2011's "Worship Music." Guitarist Scott Ian previously confirmed that the group had written seven songs, so it would seem that the new album making is heading along as planned. The drummer also posted a video of himself working on new drum fills, quite possibly involving tracks from the upcoming record. "We are writing and demoing right now," Benante briefly commented on the video. Later last month, Ian gave a more detailed set of new info, announcing "aggressive, fast, even riff-ier" record. "Charlie, Frankie and I are working hard at new Anthrax," he said via official blog. "We've had a couple of writing sessions and things are moving along well, fast for us actually. We've got seven songs arranged musically and we're getting together again in a week and a half." As the latest Anthrax studio release, "Worship Music" dropped in September 2011, peaking at No. 12 on the Billboard 200 chart with 28,000 copies sold in the US within the first week.
