Boston punk rock band Grass Is Green make spontaneous and angular music, and hinted at a new album when they played the Exploding In Sound CMJ showcase. Their set that night was definitely a sign of good things on the way, and now they’ve officially announced Vacation Vinny and dropped blistering, album-closing single “Vacation 2.0″ which jerks and jumps its way through three thrashy minutes before breaking into a wailing coda. It’s smart as hell but you can still mosh to it, part of why it’s not at all surprising that they’re going on tour with Speedy Ortiz next year.

Vacation Vinny is out 1/14 2014 via Exploding In Sound. Pre-order it here.
