Experimental-noise newcomers Service have released an aggressive debut EP, cheekily titled CHARM. The Boston quartet covers plenty of ground in the three track release, shifting from assertive punk dudes to meandering noise-heads by opening up tight, mathy structures into longform explorations. Though the momentum of CHARM dips from intensely focused to wayward abstraction, the volume is always up to 10, and there’s a great deal of integrity behind every note. Check out Service on December 17th at Deep Thoughts in Jamaica Plain, doors at 8pm. -Charley Ruddell
