UK techno producer Andy Stott’s Decibel Fest performance last year sounded like the intro to Black Sabbath’s “Iron Man” set to a Robitussin’d 4/4 kick-drum pulse; some asses are still suffering trauma. With his newest album, Luxury Problems, Stott adds the vocals of his female former piano teacher and lightens the coal-black mood a tad for a slightly more palatable take on the chilling, narcotized techno that marks his best works. This is severe, sinisterly sexy dance music. Get (way) down. (Crocodile, 2200 Second Ave,, 9 pm, $15, 21+)
