Multi-platinum-selling rockers 3 Doors Down [ tickets ] are back with new music and a slate of spring dates that will lead into a worldwide tour this summer.

The band is currently scheduled to visit more than a dozen US cities this spring, starting March 20 in Panama City Beach, FL, and sticking primarily to the Southeast through mid-May. A July 4 show is also booked on the Hawaiian island of Oahu. Details are listed below.

The bandmates have been in the studio for the last 11 months working on their fourth album, according to a blog posting at their MySpace page. The self-titled set, due May 6, follows 2005's "Seventeen Days," which debuted at the top of The Billboard 200.

The new record's lead single, "It's Not My Time," was serviced to radio last week and is currently making waves on mainstream-rock, modern-rock and pop charts. Another single, "Citizen Soldier," has been featured in a major promotional campaign for the National Guard, according to various reports. Samples of those songs are streaming at 3 Doors Down's MySpace page.

The Mississippi/Nashville-based group has sold 13 million albums since its 2000 debut, "The Better Life," which has gone six-times platinum on the strength of mega hits including "Loser," "Kryptonite," "Duck and Run" and "Be Like That."
