In a potentially alarming stroke of convergence, AC Entertainment has booked the recently reunited Phish at Thompson-Boling Arena on June 10, the day before the band heads to Bonnaroo. The Knoxville show sold out the arena in hours last week. That means every Phish fan within a day’s drive could descend on Knoxville in a cloud of patchouli, pot smoke, and tie-dye fumes this summer. Start preparing yourself. Meanwhile, AC also officially announced Bruce Springsteen as Bonnaroo’s co-headliner. Can we get him, too?
