As we wrap up day 3 of Ultra Music Festival, we are once again graced by a stellar performance from Jack U, the formed DJ duo moniker from Diplo and Skrillex. The duo took the Ultra Mainstage and celebrated their world premiere festival performance of JACK U with the hundreds of thousands that took to Bayfront Park. With a diverse and uniquely styled set with bass infused sounds, the duo made their mark on an already busy weekend in Miami. Take a listen to the one hour set below. Enjoy!
