The Postal Service released just one album—2003's Give Up—but their frothy, meditative electro-pop still exerts a powerful influence on indie music. The duo's shadow looms large over Grizzly Bear's haunting spin on sunny California pop, Passion Pit's prickly synth bangers, and Owl City's modest emo-pop, in which Adam Young airily coos with the lovesick innocence of a young Ben Gibbard.
