Gov’t Mule is currently in the midst of West Coast tour in advance of its new studio album By a Thread. On Saturday the band performed at Jacksonville, OR’s Britt Pavilion. The group returned for a two-song encore as well with guitarist Jeff Pevar, a veteran of Jazz is Dead and David Crosby’s various bands. Pevar sat in with the group for “Need Your Love So Bad” and Crosby’s “Almost Cut My Hair.” Gov’t Mule will appear at Salt Lake City, UT’s The Depot tomorrow.
