Last time the Mad Decent Block Party rolled through Brooklyn, the indie label behind it brought Riff Raff, Lunice, Bonde Do Role, a kid named Baauer, and, of course, Major Lazor, the rave-dancehall trio led by CEO Diplo, to a rainy lot near the East River. In the year since, Baauer’s “Harlem Shake” gave the label their first chart-topper, and they’ve expanded the festival accordingly, sending it across the country and, for the first time ever, charging for tickets. Still, another strong lineup makes the price seem like a bargain: party-starters Matt & Kim, Dillon Francis, Flosstradamus, DJ Sliink, 3Ball MTY (a Mexican crew that will surely convert a few locals), and, 
yes, Major Lazer highlight a long, diverse day of dancing. Here’s hoping the rain holds off.
