The third edition of the Sounds of the Underground tour will feature performances by GWAR, Chimaira, Every Time I Die, Necro and Job For A Cowboy, among others.

The 25-city North American trek starts July 6 at the Palladium Ballroom in Dallas and wraps Aug. 8 at the Fillmore Auditorium in Denver. Other confirmed acts include Darkest Hour, Amon Amarth, the Acacia Strain, Heavy Heavy Low Low, the Number Twelve Looks Like You, Devil Wears Prada and Goatwhore.

GWAR is scheduled to headline on most nights, and additional as-yet-unannounced guest headliners will join the bill on select dates. This Is Hell and 2 Cents will split the tour in half as opening acts.

"There are a few bands that have been on the tour before and a bunch of newcomers," the Agency Group's Tim Borror tells And as opposed to other heavy metal summer tour packages, SOTU is "trying to be the niche, off-the-radar, less commercialized type of tour," he says.

The Live Nation-produced summer jaunt is visiting 2,000-to 5,000-seat venues, including large ballrooms, cut-down arenas, convention centers and outdoor stage setups. Borror says this year's SOTU is hitting smaller venues than it has in the past. "The last couple of years we've done this big parking lot-esque type of tour," he explains. "We're going to try and have a more controlled atmosphere that's a lot less expensive to produce."

Ticket presales begin April 25 at a price of under $30, according to Borror.

Hot Topic is the presenting sponsor of this year's SOTU. In late June, the retail chain will carry an exclusive CD/DVD compilation of the summer trek.

Last year's SOTU, which featured As I Lay Dying, In Flames, Trivium, Cannibal Corpse, GWAR, Terror, the Black Dahlia Murder, the Chariot and Through The Eyes Of The Dead, grossed $1.8 million from 18 shows reported to Billboard Boxscore.
