Mad Decent Block Party kicks off again this summer in just four days, with the first sweat-T-shirt contest going down July 19th in Calgary, then another in Las Vegas the day after. Over the course of the summer, the tour will feature performances by Diplo, Danny Brown, Riff Raff, Lunice, Skream and many more. Tickets to the first weekend, plus shows in Philly, DC, New York, LA and other cities are available now. The whole series is sponsored by FADER.
