Allman Brothers Band fans of a certain age may remember Duane Betts as a teenager taking the stage to sit in with his father, Dickey, and the ABB in the mid ’90s. But 30 years later, the younger Betts has been around the block a few times, touring with his father for more than a decade, playing with California folk-rockers Dawes for a stretch, and forming the Allman Betts Band with Devon Allman. Together, they recorded two albums and toured extensively.
