Family ties are part of the fabric of American roots music. How often have we read (and for Pete’s sake how often have I written) that Artist X “came from a musical family”? The connection among siblings and the passing of ideas across generations might be the central reason this music sustains, and that in turn sustains us. Wednesday night offered up heart lifting performances by a first son of bluegrass and a first brother of Americana soul, plus a delightful country newcomer and a set by our own soul brother Jim Lauderdale.
