This past weekend, Friday, March 26 and Saturday, March 27, over 100,000 music enthusiasts descended on Miami's Bicentennial Park for the 12th annual Ultra Music Festival (UMF), drawing its largest attendance numbers ever.  Both days were sold-out.  This astounding number also marks the first time ever an event has sold out, let alone for two days, Bicentennial Park. The festival was also the recipient of an IDMA (International Dance Music Award) for "Best Music Event" for its fifth year in a row.

Over 200 international leading electronic music performers, DJs and cutting-edge bands alongside Miami regional artists performed over the two-day extravaganza.

Akshay Bhansali of MTV News wrote,

"Dance music's biggest weekend in America kicked off with a series of powerful performances. With a multitude of stages (and even a Heineken-inspired dome), the weekend's lineup is probably UMC's largest and most star-studded grouping yet."

The festival's stellar line-up was spearheaded by Friday's mainstage headliner Tiësto and Saturday's headliner Deadmau5.

Over 1.4 million people in 178 countries logged on to watch a stream of two of the festival's 10 stages. During that time 65,000 chat messages were exchanged about it.

Highlights of Ultra encompassed several guest appearances. On Friday, March 26, France's David Guetta was joined by Lil Jon, LMFAO and the Black Eyed Peas' will.i.am and Apl.de.ap, while Felix Da Housecat welcomed Sean "Diddy" Combs.  On Saturday, March 27, Kelis joined Benny Bennasi for their song "Spaceship" and the Guetta-produced track "Acapella."  Florence from Florence and the Machine graced the stage during Swedish House Mafia's set; and drummer Tommy Lee along with vocalist Sofia Toufa joined deadmau5 to debut a brand-new untitled song during his closing set!  Other special guests in attendance were singer Macy Gray and TV personality Kelly Bensimon of The Real Housewives of New York.

In a word, the performances were SICK!  Next year will be even wilder as UMF just announced that its 2011 festival will be 3 days long!  I can't wait!!
