Amid the oppressive early-day heat of this year’s Pitchfork music festival in Chicago, Barcelona’s Delorean turned out to be one of the weekend’s biggest surprises, blasting through an audacious and energetic set to an appreciative, if only half-awake, crowd. With its blaring reggaeton horn and propulsive dance beats, the band worked hard to dispel the myth that everyone playing keyboard-dominated music must bury their face in their knobs. After garnering heavy buzz last year with its Ayrton Senna EP, an easygoing collection of shimmery pop with Animal Collective-like flourishes, the band released a more assured debut full-length, Subiza. Emboldened by both Spain’s thriving techno culture and American mid-’90s electronica, songs like “Stay Close” and “Real Love” have an immediate snap live, likely to transform even the most taciturn wallflower at the Rock & Roll Hotel into a Brightest Young Thing.

DELOREAN PERFORMS WITH LEMONADE AT 8:30 P.M. ON TUESDAY, NOV. 23, AT ROCK & ROLL HOTEL, 1353 H ST. NE. $12-$14. (202) 388-ROCK.
