In June 2013, American jam-rock band Gov't Mule—led by Warren Haynes and renowned for improvisational sets blending blues, rock, and psychedelia on albums like Shout! (2013)—performed at Bonnaroo Music and Arts Festival, an annual event launched in 2002 in Manchester, Tennessee, as a platform for alternative music emphasizing jam bands among 80,000 at Great Stage Park. Their 90-minute Which Stage set, captured professionally, embodied their American tour climax, where Haynes's guitar solos merged with Matt Abts' drum power and Jorgen Carlsson's bass lines to spark euphoria under summer sun. Part of a lineup with Paul McCartney and Tom Petty, this show highlighted Gov't Mule's mastery of live sound, turning the festival grounds into a realm of collective trance.
