Rascal Flatts will travel across the U.S. with three more country groups this summer as they launch the American Band tour. Little Big Town, the Eli Young Band and Edens Edge will open the series of shows, which begin June 15 in Hartford, Conn.

"We are always looking for new ways to re-energize our live shows," says Jay DeMarcus of Rascal Flatts. "We thought bringing out these bands, who are among some of our favorite vocal groups, would make a great night of entertainment!"

Rascal Flatts' upcoming album, Changed, will be released on April 3. Little Big Town is also planning to release a new album in early 2012.

Meanwhile, the Eli Young Band recently scored their first No. 1 hit with "Crazy Girl." Their new single is "Even if It Breaks Your Heart." New group Edens Edge is currently climbing the chart with "Amen." They are preparing a full-length debut album for release later this year.

In addition, Thompson Square will replace Eli Young Band on two of the tour dates -- July 13 in Dallas and July 14 in Houston.

The tour is scheduled through early September, although some specific dates have not yet been determined.
