Sondre Lerche counts A-Ha, the Beach Boys, Elvis Costello, and Cole Porter as his influences. That might explain why the Norwegian troubadour became such a hit among American indie-rock devotees when he released his first album in 2002 at the tender age of 19. He’s since released three more albums, and he gained a broader recognition last year for his contributions to the soundtrack to Dan in Real Life. His live shows integrate the infectious power pop of boy-band acts (not to mention the doe-eyed look), complex jazz riffs, and a knack for finely crafted songs, which range from the beautifully sad to the toe-tappingly, clap-along snappy. Tonight he breezes into the Paradise Rock Club (967 Comm Ave, Boston, 617.562.8800) at 9 p.m. Doors open at 8; tickets ($17) are general admission.
