System of a Down drummer John Dolmayan recently gave an update on his upcoming solo cover album, confirming the making process is heading along as planned. "Work on my as yet untitled solo/covers album is going well, we've completed basic structure and beats for eight songs so far. I'll update you as more develops," the drummer noted via Facebook. Although Dolmayan didn't specify which tracks he will be covering, he did confirm that Slayer tunes are definitely out of the question. Replying to a fan suggestion to cover the thrash titans, the drummer explained: "Slayer should never be covered, there's no way to improve their songs." John also briefly addressed the new SOAD album, simply adding that "when there is [an album] in the works, I'll mention it." With little to no updates on the new studio release, the band's fans have grown quite impatient for the four-piece to finally hit the studio. The latest SOAD studio effort, "Hypnotize," saw its release in November 2005 through American Recordings, landing at No. 1 on the Billboard 200 chart with 320,000 units shipped in the US within the first week.
