Amid the minefield of husband-and-wife duo divorces, Susan Tedeschi and Derek Trucks are a testament to the institution of marriage and the power of the nondenominational church of the Allman Brothers Band. That doesn't mean it's all power ballads and acoustic harmonizing, though. When the horn section gets involved, it all begins to feel like an orgy in your ears. With special guests Richard Thompson, the Wood Brothers, and Leon Russell.
Thu., Sept. 20, 8:20 p.m.; Fri., Sept. 21, 8:20 p.m.; Sat., Sept. 22, 8:20 p.m., 2012
