The ninth edition of the festival wrapped up Sunday night with headliner Dave Matthews Band. Jay-Z and Stevie Wonder headlined the main stage on Saturday; Kings of Leon had the honor on Friday.
Ashley Capps, co-founder of Bonnaroo and president of festival co-producer AC Entertainment, said attendance was more than 75,000, but slightly less than sold-out.
Temperatures were in the mid-90s most of the weekend, with the heat index at more than 100. Capps said that for the most part, festival attendees stayed healthy. Coffee County Sheriff Steve Graves said arrests were "about normal." More than 50 had been arrested as of Sunday afternoon.
More than 100 other acts performed on five main stages and assorted smaller ones, scattered throughout the 650-acre site.
The Saturday evening double bill of headliner Jay-Z and Stevie Wonder was the apex. Introducing Wonder, Conan O'Brien shouted to the crowd: "All the mud, all the rain, all the heat it's all worth it.''
O'Brien was the most omnipresent figure at this year's Bonnaroo. The comedian twice performed his "Legally Prohibited From Being Funny on Television'' show, and he played master of ceremonies on the main stage Friday and Saturday.
"In six months, I've gone from hosting 'The Tonight Show' to performing at a refugee camp,'' O'Brien, who begins a new show for TBS in November, said Friday.
