For its latest album, Seven Devils, this folk-rock group took inspiration from a literary classic. The songs allude to Dante's epic voyage through the Nine Circles of Hell. Of course, with twangy guitars and banjos, the tunes get a bluegrass/alt-country makeover. The band performs tonight at 8 at the Beachland Ballroom. Cris Jacobs opens. He's touring support of the forthcoming One of These Days, his first album in five years.
