Ultra Music Festival 2011 SROs

MIAMI (CelebrityAccess MediaWire) — The North American festival season may be off to a good start after organizers for the dance music festival Ultra announced that tickets to this year's event have completely sold out.

Set to take place from March 25 to 27, at Bicentennial Park in Miami, this year's Ultra will be headlined by Tiësto, deadmau5, The Chemical Brothers, David Guetta, Carl Cox and Empire of the Sun and is expected to draw more than 150,000 fans. This year will also mark the first year that the festival expands from a 2-day to a 3-day format.

Originally launched in 1999 as a one-day electronic music event and timed to coincide with Winter Music Conference, an annual electronic music gathering that also takes place in Miami, the festival expanded to 2-days in 2007 and has become one of the highest grossing festivals in the world. 2011 will be the first year that Ultra steps away from the annual Winter Music Conference, also held in Miami, with organizers citing insurmountable logistical issues. Event organizers, in a statement issued in November, noted that they hope to re-align with WMC in 2012.

While the festival does focus on dance and electronic music, they have, in recent years, expanded their focus to include acts that have been influenced by edm and this year's Ultra will also feature artists such as Duran Duran, Holy Ghost!, The Klaxons, the Disco Biscuits and Erasure.

Ultra is also expanding into other markets and this year will be staging an Ultra Music Festival in dance music mecca Ibiza as well as San Paulo, Brazil on November 6th. – CelebrityAccess Staff Writers
