The Mad Decent Block Party lineup is stacked, but what did you really expect? After the announcement of the tour and its locations, the event released the list of artists who will be partaking in the neighborhood festivities. Newbies to the party are Outkast, Flume, What So Not and the illustrious Jack U, among others. Diplo will not be participating in these events with Major Lazer, but you can still catch his two cohorts performing at the party. Other old faces like Dillon Francis, GRiZ and Riff Raff will be in attendance, so be sure to check them out as well! Tickets are currently on sale; you may buy them here.
