Boost your mood with Passion Pit

Passion Pit's helium-buoyant synth pop belies the longing and uncertainty at its core. It's the sound of sunshine, though the subject matter here is more suited for overcast days. Still, all the bright buzzing keys, dizzy falsetto vocals and supersized hooks are meant to boost the kind of sullen moods that seem to catalyze some of the band's tunes.

See Passion Pit at 9 p.m. Thursday in the House of Blues at Mandalay Bay, 3950 Las Vegas Blvd. South. Tickets are $33 in advance, $35 day of show; call 632-7600.
