With the recent release of their debut album, “Not Haunted,”The Violet Hour have just begun to explore the sounds that define them. With blues, punk and indie-rock influences, the band delivers driving bass lines and artful drumming that set the stage for upbeat guitar work, ruthless vocals and a smattering of synth. It’s a dirtier kind of a rock with a blues-infused edge. It’s grungy and gritty. It’s dynamic and catchy. And it’s not afraid to show its dark side. Tune into WMSE’s Local/Live tonight at 8pm to listen — WMSE.org or 91.7 FM on the dial.
