“I was 22, alone with nothing to do,” sings Adam Young on “I Live Alone.” That’s roughly the story of Sky Sailing, which preceded his other one-man band, the multiplatinum Owl City. The latter resembled the Postal Service, and this set, mostly completed in 2007, recalls Ben Gibbard’s other band, Death Cab for Cutie. Young’s songwriting is often lean, and with acoustic textures replacing Owl City’s synth beats, his dreamy introspection takes center stage. On “Sailboats,” he even pledges his achy love to Audrey Hepburn. Evidently, the kid always dreamed big.
