Rounder Records will issue the disc on September 20, which is the group’s first studio recording with founding members Gary Louris and Mark Olson since 1995’s Tomorrow the Green Grass. The band will celebrate the disc with an appearance on the Late Show with David Letterman on September 23. An extended US tour will then open in October.
