After missing the capacity mark in 2005, Bonnaroo has now once again sold out in advance. Bonnaroo's allotment of 80,000 tickets was sold entirely through the festival's Web site. Set to take place this weekend, the three-day camping and music festival will once again be held on the same 700-plus-acre farm in Manchester, Tenn., 60 miles southeast of Nashville.

"We're psyched," A.C. Entertainment president Ashley Capps tells Billboard. "Every year, our vision for Bonnaroo is the same: creating the very best music festival that we can imagine. Ultimately, though, it's the fans who let us know how we're doing, and I think this indicates that we're still on the right track."

Now in its fifth year, Bonnaroo has become the top-grossing festival in the world, based on numbers reported to Billboard Boxscore. Last year, it took in $13.4 million and drew 76,049 people, just short of the sellout mark of 80,000.

In 2004, Bonnaroo grossed $14.5 million and drew 90,000; capacity was then lowered by 10,000 to improve the fan experience, according to festival producers Superfly Productions and A.C. Entertainment.

Along with headliners Radiohead, Tom Petty and the Heartbreakers and Phil Lesh and Friends, Bonnaroo will present well over 100 acts on its nine stages. In addition to its music lineup, non-music attractions like a cinema, a comedy tent and an onsite beer festival will be available 24 hours a day.

Fans without tickets will still have a chance to witness the action as it unfolds, as the AT&T Blueroom will offer a live Webcast of select performances at blueroom.att.com. To visit Billboard.com's Bonnaroo microsite, click here.
