There’s something special about old friends reuniting to make music, revisiting old glories and perhaps forging a few new ones. When they’re as talented as the Notorious Cherry Bombs, the audience’s share of the payout is substantial. The band centers around Rodney Crowell, who plucked other members of Emmylou Harris’ mid-’70s backing band — including Vince Gill, keyboardist/music exec Tony Brown, and in-demand studio pros bassist Emory Gordy, the late drummer Larrie London and guitarist Richard Bennett — to create the Cherry Bombs. They backed Crowell’s ’78 solo debut, and reunited in ’04 (with Eddie Bayers on drums) to release their fine self-titled country-rock debut. Given their lengthy pedigree it’s no surprise they cover the country music spectrum — from more traditional country-and-Western swing to whiskey-scarred country rawk with ample aplomb. Proceeds from the show will benefit the W.O. Smith Music School, whose volunteers offer inexpensive music instruction to low-income children.
