On Friday, the first day of Ultra 12, the weather didn't look very promising. Fortunately, although the clouds remained, the weather held up and the Ultra Music Festival was a huge success once again.

People from all over the world attended the electronic music festival in Miami, Florida on Friday, March 26 and Saturday, March 27, 2010. Headlining acts included Tiesto, David Guetta, Groove Armada, Deadmau5, Swedish House Mafia, Armin Van Buuren, Faithless Sound System, Benny Benassi, Damian Marley, Passion Pit, and Little Boots. Those were just some of the artists on the Main Stage.

The Bayfront Live Stage saw performances from The Disco Biscuits, The Crystal Method, Rabbit in the Moon, Infected Mushroom, Orbital, and Bloody Beetroots. In the Carl Cox & Friends Arena, fans saw Carl Cox, Green Velvet, Sasha and John Digweed, Erick Morillo, Fedde Le Grand, and Yousef. On Friday, the UMF Ibiza Tent featured Eric Prydz, Dirty South, Will.I.Am, Kaskade, and Felix Da Housecat.
