Sing-Sing combines stylish spy-movie ambiance, giddy girl-group harmonies, warm-toned electro-noises, graceful vocal phrasings and psychedelic guitar shards. For the most part, these are relentlessly pleasant, unfailingly melodic backdrops. Lyrically, though, hints of violence invade these serene settings. "Break my bones just to talk to you," O'Neill sings during a creepy statement on celebrity obsession cloaked as a love song, and then "promises if you ever feel alone/He will break her legs and bring her home" during an otherwise upbeat ode to a spiritual healer. "Going Out Tonight" starts perky, then detours into an eerie psychedelic haze as its club-hopping protagonist groggily realizes she's in a strange bed. On this album, romance comes with a cast and crutches and rude awakenings disrupt delicate dreamworlds.
