As the O+ Festival takes over Kingston, eight of Hudson Valley’s loudest bands will join forces to put on a pair of dark and heavy shows that might as well be called the B Negative Festival. “Two Nights of Heavy” will be held at Snapper Magee’s, our area’s best punk rock dive bar. These bands will drench the room with ear-throbbing sound and electric energy. Dead Operator, Shadow Witch, Shadow Witch and The Nighttimes will play the first night, Pitchfork Militia, Waster, Grim Exit and Adalusion play the second. Celebrate Kingston’s status as a hub for heaviness with cheap drinks and a $5 cover charge.
