The first ever Ultra Music Festival in Buenos Aires is next weekend! (Get in on it before it becomes ghetto in a couple years.) Headliners including Justice, John Digweed and Kaskade will be here next Saturday, May 5, at Costanera Sur in Puerto Madero. There will be a main stage, a trance stage and a techno stage. Tickets were sold by Ticketek and were A$R 310 with all fees included, but they're sold out now. Try you're luck on Mercado Libre.
