By the summer of 2005, the ALLMAN BROTHERS BAND had moved into a comfort zone of stability and superb chemistry. The lineup —Gregg Allman on vocals and keyboards, drummers Jaimoe and Butch Trucks,Warren Haynes and Derek Truckson guitars,Oteil Burbridge on bass and percussionist Marc Quinones— had been together since 2001 and had established a groove, both on and off the stage.
