Southern California metal outfit Atreyu [ tickets ] will take to the road this fall alongside Hollywood Undead in support of its impending new album, "Congregation of the Damned."

After a handful of one-off performances to round out the summer, Atreyu will start the co-headlining trek Oct. 16 in Lubbock, TX. The 27-date run, which hits clubs throughout the US and parts of Canada, will finish along the West Coast, with the final show slated for Nov. 20 in Las Vegas. Details are shown below.

"Congregation of the Damned," Atreyu's fifth studio effort and second with Hollywood Records, is due in stores Oct. 27. The band recorded the new album at Los Angeles' Henson Studios with the help of producer Bob Marlette (Ozzy Osbourne, Airborne).

"I think this is the longest our band has ever had laser-like focus on an album," frontman Alex Varkatzas said in a press release. "We were all working together really well and we had a great time in the studio with Bob. He's this jovial, cigar-smoking, goatee-sporting dude from Nebraska, and he really helped us finetune the material and nail our best performances."

The forthcoming release follows 2007's "Lead Sails Paper Anchor," which debuted at No. 8 on The Billboard 200 and produced three Top 20 singles"Becoming the Bull," "Falling Down" and "Slow Burn."

Los Angeles-based raprock outfit Hollywood Undead is supporting its debut album,"Swan Songs," which surfaced last fall.
