Nashville post-punk rocker Seth Sutton doesn’t seem to pause much these days. With no less than three bands, and a new album and tour for his band Useless Eaters, Sutton writes, records and performs at a pace nearly as frenetic as his music. Useless Eaters hit Chicago’s Empty Bottle Friday night, but start off the weekend with a stop in on The Morning Shift for an edge-of-your-seat punk explosion.
