Last week, New Hampshire screamo outfit Old Gray announced Slow Burn, the band’s second full-length album. During the course of the band’s five-year existence, it’s played with the genre’s form more than most, opting not to see the interplay between screamo’s loud/quiet dynamics as something limiting, but as a sound that’s endlessly expansive. This broad perspective is aided by the fact that Old Gray guitarist-vocalist, Cameron Boucher, is a musical journeyman: In addition to also playing in the pop-punk act Sorority Noise, and releasing dour covers under his own name, he’s been behind the boards on records that only highlight his range.
