Canadian rock outfit Hot Hot Heat will return in the fall with its next album, "Happiness LTD." Due Sept. 11 via Sire, the project was co-produced by the band with Butch Walker, Tim Palmer and Rob Cavallo.

Tracks include "Outta Heart," which frontman Steve Bays calls "the most non-Hot Hot Heat song we've ever done," and "Harmonicas & Tambourines," which features four drum kits playing at once.

"It covers the journey from bliss to misery and the attempt to get back to bliss, while acknowledging how exciting the ride can be in between," Bays adds of the album.

"Happiness LTD." is the follow-up to 2005's "Elevator," which has sold 204,000 copies in the United States, according to Nielsen SoundScan. It spawned the Modern Rock chart singles "Middle of Nowhere" (No. 23) and "Goodnight, Goodnight" (No. 27).

Hot Hot Heat will debut new material during a run of U.S. shows that begins tomorrow (May 10) in Oklahoma City.
