Teen is five women, five friends, three of them sisters, a collective force known as the Liebersons, daughters of famed composer Peter Lieberson, who taught his kids to sing like angels, and taught them well. They’re classically trained, their voices precise and clean, but Teen comes at you with a sound that’s raucous and angst-ridden. A little bit dirty. A little bit mean. The sisters—Lizzie, Teeny (Kristina), and Katherine—trade instruments and solos with close friends Jane Herships and Maia Ibar. The rules are loose, and at times improvised, so that the hard, clear songs feel like a series of happy accidents, a beautifully productive misstep.
