Metal monsters Mastodon [ tickets ] have extended their current headlining tour, unveiling new dates through the end of March as the band continues to flex its muscles as a headlining act.

Currently in Pittsburgh, where the band will continue its outing tonight (2/9), Mastodon is getting support on the trek from fellow metal acts Converge [ tickets ] and Priestess [ tickets ]. The group's itinerary is included below.

Mastodon is backing "Blood Mountain," its third studio album and first since signing with the Warner Bros. imprint Reprise Records. The disc, which hit stores in September, follows 2004's "Leviathan."

The new album is also available in a CD/DVD package, including expanded artwork, a behind-the-scenes look at the making of the album, a gallery of still images taken during the recording process and a live video of the track "Capillarian Crest."

"This album is a nice collaboration of everybody's character and individuality," singer/bassist Troy Sanders said in a press release. "I always felt we were four unique individuals making up the band, and we've combined to make a meal with wicked ingredients. But most important, everything we do is completely pure and honest."

Boston-based Converge released its sixth studio set, "No Heroes," in October, while Montreal natives Priestess recently offered up their debut effort, "Hello Master."
