In addition to their already-announced docket of 2016 shows with artists including Chuck Mead, Aaron Lee Tasjan and the Hillbenders, Bluegrass Underground has revealed the lineup for its next taping weekend. Twelve artists are next to play the Volcano Room inside McMinnville’s Cumberland Caverns April 1–3, all for a taping of the concert series’ PBS special. Americana’s favorite musical duo, Dave Rawlings and Gillian Welch, will take the stage with the Dave Rawlings Machine project, with folk outfit Hurray for Riff Raff opening, among others. Brooklyn-based trio the Lone Bellow will also play the cave alongside Alabama soul-rock favorites St. Paul and the Broken Bones and Florida jam band JJ Grey & Mofro.
