The Dallas-based orchestral pop ensemble is touring in support of its sophomore album Together We’re Heavy and has pulled off a full slate of summer tour dates in the wake of the canceled Lollapolooza tour.

In additional to the concerts, a number of TV performances are also on the way from the Spree. An appearance on “Late Show with David Letterman” has been confirmed for an August 27 air date. In early August the Spree will tape an episode of PBS’ “Austin City Limits,” which will air in November. A recently-taped performance on CBS’ “The Late Late Show with Craig Kilborn” airs Tuesday, July 27.

Together We’re Heavy was released in the U.S. by Hollywood Records on July 13, and is currently No.1 on Soundscan’s Top New Artist Albums chart.
