Metro Station will launch its "Disco Balls" trek Oct. 15 in Nashville and play 35 clubs and theaters across the US through late November. Support acts include alt-hip-hop duo Shwayze, pop rapper Tyga and New Jersey popsters Cash Cash. Metro Station's full itinerary is listed below.

The Hollywood, CA-based quartet is backing its self-titled debut, which surfaced last September and climbed into the Top 40 on The Billboard 200 earlier this month. The bandmates performed the album's first pop/dance hit, "Shake It," during their national television debut on ABC's "Good Morning America" last week, and they'll return to the small screen for a Sept. 4 appearance on "Jimmy Kimmel Live!"

"Shake It" has been used in television spots for the "What Happens In Vegas ..." advertising campaign and was chosen as the official theme song for the 2008 Teen Choice Awards. Metro Station's new single, "Seventeen Forever," is featured on the soundtrack for the film "The Sisterhood of the Traveling Pants 2," which is currently in theaters. Both songs are streaming at the band's MySpace page.

The group of teens--vocalist/guitarist Trace Cyrus (stepson of Billy Ray Cyrus and half-brother of Miley Cyrus), vocalist/guitarist Mason Musso, keyboardist Blake Healy and percussionist Anthony Improgo--started scoring national press before they signed their record deal with Red Ink in late 2006. They built a dedicated legion of fans through MySpace and shot up the social-networking site's unsigned bands chart with "Seventeen Forever."

"The fans did everything," Musso recalled in Metro Station's bio. "We never went out looking to play shows or gain publicity, but we did because of our amazing fan base in L.A. These kids would help us book shows and then make the flyers themselves for us to post up. It was kind of insane, actually. It just steamrolled."
