Today SHINee had the honor of appearing on stage at UMF Korea , or the Ultra Music Festival , with Beatburger . UMF, which takes place annually, is the world's most famous outdoor electronica festival. The festival was originally created with a focus on electronica, but it has grown over the years to showcase music from the biggest and best EMD (electronic dance music) artists to crossover EMD artists. The festival takes place in Miami, Brazil, Argentina, Chile, Ibiza and Korea, and thousands of people come from all over to attend. So, to have SHINee perform there is pretty much a big deal.
