“ Sometimes you have to remind yourself why you started something in the first place, ” muses Seth Walker. On his stellar new album, Gotta Get Back , he does precisely that, excavating the roots of his love affair with music and reuniting with the family that helped spark the fire all those years ago. The record is as remarkable as the story behind it, which stretches from Walker’s childhood living on a commune in North Carolina to stints in Austin, Nashville, New York and New Orleans.
