Reggae-rock crew 311 will ring in the spring with a new studio album and a U.S. tour to match. The coast-to-coast circuit begins April 15 at Rialto Theatre in Tuscon, AZ, and concludes May 15 at Shrine Mosque in Springfield, MO.

The theater/club tour will hit nearly 20 cities, including an April 21 show at The Valarium in Knoxville, TN, an April 26 gig at Ruth Eckerd Hall in Clearwater, FL, a May 4-5 stand at The Orange Peel in Asheville, NC, and a May 14 session at Cain's Ballroom in Tulsa, OK. Supporting acts have not been announced yet.

The band is touring in support of the group's ninth studio album, "Uplifter." Recording on the project was completed in late January, and an approximate release has been set for late spring. The album was produced by Bob Rock, who also has worked with Metallica and Aerosmith, among others.

The upcoming album will be the first release from the band since 2005's "Don't Tread On Me," which peaked at No. 5 on the Billboard 200. The record and tour will feature the usual 311 lineup of vocalist Doug "SA" Martinez, lead guitarist Tim Mahoney, rhythm guitarist Nick Hexum, bassist Aaron "P-Nut" Wills, and drummer Chad Sexton.

In early June, 311 also plans to launch its annual summer Unity Tour, which primarily visits amphitheaters across the country. Supporting bands for the summer trek will be announced at a future date. Last year's outing ran from late June through early August and featured rapper Snoop Dogg and special guest Fiction Plane.
