Last night Diamond Rugs (the collaboration between John McCauley (Deer Tick), Robbie Crowell (Deer Tick), Ian Saint Pe (The Black Lips), Steve Berlin (Los Lobos), Hardy Morris (Dead Confederate) and Bryan Dufresne (Six Finger Satellite)) played CBS’ Late Show With David Letterman after this past weekend opening for the Alabama Shakes at Summerstage. The band played a grunge-era-reminder rendition of “Blue Mountains,” the single from their debut self-titled full-length.

No tour dates set, but will keep an eye on them for you.
