Dierks Bentley will launch his Up on the Ridge tour, named for his upcoming bluegrass album, on April 21 in Portland, Ore. The 24-city tour will conclude at the Ryman Auditorium in Nashville on May 22. During the tour, Bentley will be backed by the Travelin' McCourys, a quartet featuring Ronnie McCoury, Rob McCoury, Jason Carter and Alan Bartram of the Del McCoury Band. Texas-based singer-songwriter Hayes Carll will open the shows. Drawing upon his bluegrass and acoustic roots influences, Up on the Ridge will be released this summer on Capitol Nashville.
