3Ball MTY (12:35 PM Saturday, Sahara): Speaking of early morning mayhem, enter Monterrey, MX’s 3Ball MTY. The trio are superstars of the tribal guarachero movement. Influenced by cumbia, but deeply rooted in the Cuban tradition of guaracha and filled with house loops, Putumayo this is not. It’s the perfect appetizer for Saturday night’s Major Lazer set and infinitely more authentic.
