Once upon a time, before indie rock appeared in beer and Apple commercials, it was impolite and raw and it dragged inner demons out on the dance floor kicking and gagging. At least that’s how Kevin Barnes, frontman for Of Montreal, likes to tell it. On his band’s albums, Barnes (who’s actually from Athens) has straddled all sorts of musical styles, setting sinister, morbid lyrics to buoyant pop melodies and, later in their discography, serving up funk and discokissed electronica. They just released their ninth project, Skeletal Lamping. Tonight they’ll mix it up with Gang Gang Dance at the Orpheum Theatre (1 Hamilton Place, Boston, 617.679.0810). Doors are at 7:30 p.m. Get tickets ($20 and $25) at www.ticketmaster.com.
