The vivid, dynamic songs of Indiana songwriter Amy O find warmth for all seasons. Her earlier work involved harmony-rich acoustic flourishes that didn’t stick to typical song structures, led instead by the stream of her incanted lyricism. Her newest album skews electric in a number of modest modes: sunny, bendy surf riffs in frenetic start-stop, mild distortion in somber dirges and strummy, smirking doo-wop. Dour chord progressions brighten, then often get hidden by clouds. Though styles are plenty, her lyrics determine the pressure system—conjuring snow, sun and hurricanes that blow and burn through empty malls and seashores where her characters quarrel and confess.
