Biggest turnoff in indie rock? A cold, almost calculated lack of emotion. On TEEN’s 2012 debut, In Limbo, the band was surely guilty of this cardinal sin, shuffling their feet through an album’s worth of otherwise well-crafted synth-pop. But with their follow-up Carolina EP, the Brooklyn quartet sheds their K-hole detachment for something more expressive, digging into reverb-soaked riffs and drums deep in the pocket, as songstress Teeny Lieberson floats ethereal, spacehead melodies from above. A year on the road has done some good for the band, as they hone in on a psych-meets-synth sound all their own.
