Rebecca Dawkins and Tim O’Donnell intertwine blues and country.   O’Donnell’s whiskey-tinged vocals are a perfect match for Rebecca Dawkins’ glorious harmonies and soaring fiddling; the two of them can sound as charming as an old-school country duet like Parton and Wagoner, or as bittersweet as that old recording of Townes Van Zandt and Emmylou Harris.  It’s roots and roll that rocks! $15 donation requested.
