French electronic duo Justice brought their giant, prog-dance jams to the Hammerstein Ballroom on Sunday night, riling up the audience with their massive beats, clever samples, and, of course, that giant glowing cross. It may not have been a church service, but we’re guessing that some kids found transcendence in the sweating, dancing masses. The duo was supported by Canadian electro duo Chromeo who helped warm things up. Our photographer Jason Demetillo was there to cover all the action.
