Melding the innocence of "Imagine" and the force of Radiohead’s "Karma Police," Boston singer/songwriter Emily Grogan‘s "Join Together" (streaming below) off her forthcoming new album ‘Strings of Light’ is an electric call to arms. Fronting a battalion of hard drums and zinging guitars, the strong-voiced Grogan deflects the ploys of authorities while surging towards freedom with her fellow strivers. Spiked with the warmth that can be heard in pop, though, this rock song doesn’t shove but rather nestles the listener to attention. While Emily Grogan doesn’t currently have any upcoming shows listed, keep watch on her Facebook for future announcements. – Zach Weg
