It’s the group’s second free show in the area in four months, so you really don’t have a reason not to see Passion Pit. The giddy electro-pop trio from Boston tore up a performance at the University of Kansas in June, setting all the college kiddos’ hearts aflutter with songs that recall, all at once, Pet Shop Boys, Daft Punk and Whitney Houston. Nary a song is devoid of funky beats, darting synth bloops, group-sing falsetto vocals and throbbing bass. As an extra bonus, the group has a downright Kanye like sensibility for tweaking vocals to sound like chipmunks. If saving money makes you wanna dance with somebody, then Thursday’s show will bring the heat.
