No parties going down tonight? No DJs you’re trying to see? Stay in! Ultra will be simulcasting the Ultra Music Festivals in Buenos Aires and Chile tonight, with the likes of Afrojack, Hardwell, Dash Berlin, Carl Cox, Armin van Buuren, and many others. The party starts at 10PM EST/7PM PST via UMF’s YouTube Page. Be there or, you know, be lonely.
