Alt-rockers Puddle of Mudd [ tickets ] will spend much of the spring touring the western portion of the US behind their fourth studio set, last year's "Volume 4: Songs in the Key of Love & Hate."

The Los Angeles-based band will kick off the run with an April 1 performance in Anaheim, CA, followed by three more shows throughout the state. The trek then moves east, visiting theaters and clubs in 14 cities before wrapping up June 30 in Milwaukee. The full itinerary is shown at right.

"Volume 4: Songs in the Key of Love & Hate," the follow-up to POM's 2007 release, "Famous," surfaced in December. The group recorded the album in Vancouver and Los Angeles with producers Brian Howes, John Kurzweg--both of whom helped on previous albums--and Brian Virtue.

Petro Papahadjopoulos created the video for the album's lead single, "Spaceship," which included guest appearances by Nitro Circus, a.k.a. action-sport legends Travis Pastrana, Jolene Van Vugt, Jim DeChamp, Andy Bell, Erik Roner, "Streetbike" Tommy Passemante, Jeremy Rawle, Gregg Godfrey and Hubert Rowland.

Puddle of Mudd recently contributed a track entitled "Shook Up The World" to the Team USA Winter Olympics soundtrack, which is currently available for download via iTunes. Proceeds from the track went to Team USA.

"Being a part of this collection of great artists in support of Team USA is inspiring," frontman Wes Scantlin said in a statement posted at the band's website. "But the greatest reward is knowing that our contribution will help athletes achieve their dreams of Olympic Gold now and into the future."
