Widespread Panic closed the 10th annual Bonnaroo Music & Arts Festival with a massive, uninterrupted 150-minute set last night. The performance was a fitting culmination of the festival’s 10th year: Widespread Panic was the first band booked at the very first Bonnaroo in 2002, and the group has headlined the festival more than any other act. As the festival’s Centeroo vendors closed their tents, the members of Widespread Panic ran through a rock-heavy set that came to a close with a segue from “Pigeons” into “Chilly Water,” “Love Tractor” and the end of “Chilly Water.” Continuing a tradition that includes surprise appearances by Herbie Hancock, Bob Weir, Steve Winwood, Robert Randolph, Warren Haynes, Dottie Peoples and the People’s Choice Choir, Col. Bruce Hampton and other guests, the band dotted its setlist with sit ins throughout the night. The MegaBlasters horns featuring Randall Bramblett—who sat in with Panic at Bonnaroo in 2002 and again in 2008—joined in for half Panic’s set, while Bruce Hornsby played keyboards on “Her Dance Needs No Body” and “Red Hot Mama.”

The show came at the end of a nearly 24-hour marathon of music. As Saturday night gradually faded into Sunday morning, The Original Meters wrapped-up their first show in four years. The New Orleans icons opened their performance with a short set, before inviting out Dr. John and Allen Toussaint for a complete recreation of Desitively Bonnaroo. After the set came to a close, members of Preservation Hall Jazz Band, My Morning Jacket, Railroad Earth and festival promoters Superfly boarded a massive Mr. T float that paraded through Centeroo towards the Cinema Tent. Portugal. The Man greeted the crowd and treated fans to a surprise, heavily-psychedelic set that included a cameo from Morning Teleportation’s Travis Goodwin, who attended the festival as a fan. Meanwhile, The String Cheese Incident brought their late-night set to a close at almost 3:45 AM with a cover of U2’s “Mysterious Ways.” STS9 also played until dawn.

Sunday afternoon’s entertainment kicked off at noon with a performance by Railroad Earth in That Tent. Gospel singer Mavis Staples, blues/hip-hop jammer G. Love & Special Sauce, indie rockers Smith Westerns, modern songstress Nicole Atkins, piano player Amos Lee and psychedelic rockers Neon Trees also performed. During her performance, Atkins invited out cello player Ben Sollee, whose festival sit in spree included appearances with My Morning Jacket, Low Anthem, Justin Townes Earle and others.

The festival’s mid-afternoon bookings, in particular, reflected Bonnaroo’s roots. Galactic—the only band to appear at Bonnaroo nine times—performed on the festival’s main What Stage with special guests Corey Henry (Rebirth Brass Band) and Corey Glover (Living Colour) while jamband icon Gregg Allman performed tracks from his new solo album Low Country Blues and Allman Brothers Band classics like “One Way Out” and “Mellissa” with his solo band. A few hours before taking the stage with Panic, frontman John Bell treated a small crowd to solo acoustic versions of Widespread numbers “Already Fried” and “Chilly Water” and discussed the importance of alternative energy on the Solar Stage with Rock the Earth founder Mark Ross (he also introduced his goddaughter Hannah, who is known to Panic fans through the Hannah’s Buddies charity shows). Both Galactic and Staples paid tribute to cover Bonnaroo performers, too: Galactic covered Led Zeppelin right before Robert Plant took the stage with Band of Joy and Staples reworked Buffalo Springfield’s “For What It’s Worth.” Iron & Wine and Cold War Kids—two indie rock bands that helped showcase the festival’s broadened scope a few years ago—also returned for the first time in a few years.

From 2002-2008, Bonnaroo’s promoters made a point to book a Grateful Dead project. While the none of the four core surviving members of the Grateful Dead performed this year, onetime touring Dead keyboardist Bruce Hornsby made his Bonnaroo debut. “It’s reminiscent of the old Dead shows, which were always the best parties in town,” Hornsby told Relix/Jambands.com. “Only updated for 2011.”

First time Bonnaroo performers The Strokes—with frontman Julian Casablanca decked out in a very un-Bonnaroo leather jacket—closed the festival’s second largest Which Stage with an extended set that featured hits like “Last Nite” and “Take It Or Leave It.” A few tents away, Bonnaroo’s annual SuperJam returned after a two-year absence. Anchored by Dr. John and The Black Keys’ Dan Auerbach—who are said to be working on some studio projects together—the SuperJam featured a selection of traditional New Orleans songs like “Iko Iko” and Dr. John signature’s such as “Right Place Wrong Time.” Throughout the set, a steady backing band consisting of My Morning Jacket drummer Patrick Hallahan—a member of Auerbach’s solo band—Poets of Rhythm drummer Max Weissenfeldt and touring Black Keys bassist Nick Movshon backed the duo. The members of The Preservation Hall Jazz Band also joined in a various points throughout the night and Dr. John showed off his skills on his original instrument, the guitar.

In certain respects, the SuperJam was the perfect summation of Bonnaroo’s first decade: a mixture of New Orleans heritage music, focused improvisation and indie-minded roots rock that felt both vintage and in the moment.
