Zac Brown made the rounds at Oak Ridge Farm during the second night of the Lockn’ Festival in Arrington, VA. The country superstar played an exciting “Zac Brown Incident” set with the String Cheese Incident, and he even sat in with Furthur for a few tunes during their performance.

Festivalgoers woke up to yet another beautiful morning in the Blue Ridge Mountains. The day started with a set from Founding Fathers, a local act featuring Chris Pandolfi and Andy Falco of the Infamous Stringdusters. Then, Pegi Young & The Survivors took the stage for their second set of the festival.

Fans of New Orleans brass music got a real treat when the Dirty Dozen Brass Band and The Soul Rebels took the stage for a joint performance. The groups repped their hometown heavily and delivered a rousing set of brass standards, as well as covers of new hits like Daft Punk’s “Get Lucky” and older hits like The Eurythmics “Sweet Dreams.” Afterward, reggae legend Jimmy Cliff then came out for an inspired set that featured some of his classics and some storytelling, along with a rendition of Johnny Nash’s “I Can See Clearly Now,” which he first covered for the Cool Runnings soundtrack in 1993.

Next came the String Cheese Incident, who opened their show with an “Outside and Inside” that moved into a rare daytime “Valley of the Jig.” “It Is It What It Is” led to a solid jam before the band switched gears to the Latin rhythms of “Yo Se.” The tune was followed by “Joyful Sound” and “Let’s Go Outside.” The set then wrapped with a cover of Talking Heads’ “This Must Be the Place (Naive Melody)” and a fun “Restless Wind.”

Furthur came out the gate strong with a funky “Shakedown Street” to open their first set. The song transitioned into “The Wheel,” “Cryptical Envelopment” and “Estimated Prophet.” The second half of the set then featured a “Cold Rain and Snow,” “Cassidy,” Candyman” and “Jack Straw.”

The crowd then turned their attention to the left stage, where Zac Brown was taking the stage with the String Cheese Incident. Brown and Cheese were joined by a few members of Brown’s band over the course of the performance, with violinist Jimmy De Martini, bassist John Driskell Hopkins and multi-instrumentalist Clay Cook making appearances. The group kicked off their set with a take on the Cheese original “Sometimes a River,” which was followed by a version of Zac Brown Band’s “The Wind.” Next came a stellar, jammed out rendition of “Close Your Eyes” and crowd-pleasing takes on Levon Helm’s “When I Go Away,” Aerosmith’s “Sweet Emotion” and Jimmy Martin’s “Freeborn Man.” The band then played two more Zac Brown Band originals, “Jump Right In” and “Who Knows,” before going into a fantastic, funky working of Bill Withers’ “Use Me,” which Cheese had not played since 2003. That song also included an ending tease of Outkast’s “So Fresh and So Clean,” with Bill Nershi exclaiming “so fresh and clean” as the song wrapped up. The set then closed with “Colorado Bluebird Sky,” and the band encored with Bob Marley’s “Could You Be Loved,” which gave Brown one more chance to show off his vocal chops.

Furthur got their final set going with a “Dark Star” that was left unfinished, though it returned a few songs later following “Eyes of the World,” “St. Stephen” and “Unbroken Chain.” Zac Brown came out to join the band for a take on “Free/Into the Mystic,” a combination of Brown’s “Free” and Van Morrison’s “Into the Mystic” that is a staple of the Zac Brown Band’s repertoire. Brown also stuck around for “Tennessee Jed” before the set came to a close with the classic “Help On The Way” > “Slipknot!” > “Franklin’s Tower” jam. Later, Brown returned for a “Touch of Grey” encore.

After the main stage sets were finished, festivalgoers headed back to their campsites or made their way to a number of other performances. Jorma Kaukonen played a surprise late night acoustic set at the The Triangle in the main camp, and Super VIP members were treated to a very special stripped down, acoustic Furthur set featuring Bob Weir, Phil Lesh and Joe Russo. The show included takes on “Me and My Uncle,” “Loose Lucy,” a version of Bob Dylan’s “When I Paint My Masterpiece” and more. The trio then encored with “Ripple.”

Lockn’ Festival continues today with sets from Furthur (who will be playing Workingman’s Dead), Widespread Panic with John Fogerty, Trey Anastasio Band, The Black Crowes, Punch Brothers, The London Souls and Love Canon. Those that are unable to attend the event can stream many of tonight’s sets via Nugs.tv. Widespread Panic will also be offering audio streams of their sets.
