Major Lazer’s Terminal 5 show did not feature an appearance from the group’s titular front man, a Jamaican commando with lazers for arms and experience fighting zombies, but Diplo and Switch (the band’s more nonfictional members) managed to put on a rocking set nonetheless. Check out their impromptu, stage-overflowing dance party — along with photos of Death, Dum Dum Girls, Ash, Wilco, Bonnie Prince Billy, Girls, Armin Van Buuren, the Temper Trap, and Sister Anne — in our regular roundup of the weekend in shows.
