This week’s Friday First spotlights “Sammy So-Sick,” the latest single from Boston alt-punks Grass Is Green. Right now, the dudes are busy hitting the road with Speedy Ortiz, but next week they’ll deliver a brand new album, Vacation Vinny, via Exploding In Sound Records. Unassuming in appearance but utterly striking when experienced live, Grass Is Green are surely poised for big things in 2014. Friday First is a weekly column featuring new releases from both local and national bands.
