If you are one of the thousands of fans who were looking forward to seeing Swedish House Mafia (SHM) perform at this year’s Ultra Music Festival (UMF), then you are in for a major disappointment. For those of you who haven’t heard yet, SHM will not be attending Ultra this year because of UMF’s exclusivity contract. This contract states that any artist who performs at Ultra cannot perform anywhere else in Miami during the entire weekend. Ultra’s selfish and monopolistic contract has definitely bit them in the butt because little did they know they would lose one of the most popular performers in their 2011 lineup.
