Chris Robinson sat in with Furthur at Morrison, CO’s Red Rocks last night. The Black Crowes singer—who was in Colorado for a performance with his Brotherhood in Aspen tonight—emerged at the start of the band’s second set to sing and play guitar on Bob Dylan’s “You Ain’t Goin’ Nowhere” and Otis Redding’s “Hard to Handle,” the latter of which was also a hit for the Crowes. Robinson also sang on “Two Souls in Communion.” Furthur will return to Red Rocks tonight while Robinson is off to the Belly Up in Aspen.
