The Allman Brothers Band is currently in the midst of the second leg of its summer tour. On Friday, the lauded group closed out its brief run with Tom Petty and the Heartbreakers at Camden, NJs Tweeter Center, inviting out Petty, keyboardist Benmont Trench, guitarist Mike Campbell and drummer Steve Ferrone for a version of Bob Dylans Highway 61 Revisited. A night later, the group returned to the south for a show at North Carolinas Alltel Pavilion Raleigh. For unknown reasons, founding drummer Jaimoe sat out of the groups performance. Throughout the night, a number of guest percussionists performed in his place, including Derek Trucks Band skin-man Yon Rico Scott, longtime auxiliary DTB percussionist Count M’butu, Gregg Allman and Friends member James van der Bogert and Oteil and the Peacemakers drummer Chris Fryer. Longtime ABB percussionist Marc Quinones also moved behind the kit for several numbers, including Smokestack Lightnin’ and Maydell.

Jaimoe returned a night later for his bands performance at Atlantas Hi-FI Buys Amphitheater, though the groups string of collaborations continued. First, Butch Trucks son Vaylor played guitar on an appropriate Hot ‘Lanta, before Susan Tedeschi added vocals to Feel So Bad. Then Oteil Burbridges brother Kofi, who performers with Derek Trucks Band, joined his brother during an extended jam in the middle of Mountain Jam. Finally, veteran Atlanta guitarist Barry Richman performed with the ABB during a show closing version of Southbound. The ABB will perform at Holmdel, NJs PNC Bank Arts Center tomorrow.
