San Francisco Bay Area metallers MACHINE HEAD have begun writing and demoing material for their new studio album, which they hope to officially start recording by next April. At least two songs have been fleshed out in demo form, with several others in the works.MACHINE HEAD's long-awaited follow-up to 2007's "The Blackening" is tentatively due late 2011 via Roadrunner Records. "The Blackening" was recorded at Sharkbite Studios in Oakland, California with MACHINE HEAD frontman Robb Flynn returning to the producer's chair, and Mark Keaton once again handling engineering duties. Longtime MACHINE HEAD collaborator Colin Richardson (CANNIBAL CORPSE, TRIVIUM, BULLET FOR MY VALENTINE) mixed the record in London. "The Blackening" — which has garnered numerous awards and enjoyed praise from both critics and fans alike since its release in 2007 — received yet another incredible honor in an issue of U.K.'s Metal Hammer magazine, having been recognized by fans and magazine staff as the "Album of the Decade." The CD, which was re-released as a "special edition" in October 2008 via Roadrunner Records, was also certified silver by the BPI (British Phonographic Industry) for U.K. sales in excess of 60,000 copies.
