Slipknot is on the road behind its third album, last year's "Vol. 3: The Subliminal Verses." After working with producer Ross Robinson on its previous two releases, the band teamed with Rick Rubin (Slayer, Red Hot Chili Peppers) this time around.

Massachusetts-based Shadows Fall is backing its latest set, "War Within," which surfaced in September. Virginia quintet Lamb of God is supporting its August release, "Ashes of the Wake."
