This year’s Ultra Music Festival marked yet again another wildly successful event for the world famous event. Throughout the entirety of the weekend, the festival saw a variety of guest appearances and highlights that included a surprise Justin Bieber performance alongside Skrillex and Diplo, as they performed their Jack U collaboration “Where Are U Now.” Usher also joined Martin Garrix on the Ultra main stage, as they performed their new collaboration “Don’t Look Down.” MAKJ even brought out O.T. Genasis to perform his mega hip-hop hit, “Coco.” These special occurrences are some of the reasons that Ultra Music Festival is one if not the most anticipated events of each year.

Even those who weren't lucky enough to attend the festival were able to part of the action with the Ultra Live stream. Now, Ultra has released the 'Thank U' video to the fans who tuned into the stream. Ultra wrote on their Facebook, "Every year, we are blown away by the top-notch crowd that descends upon Downtown Miami and the incredible moments that we get to share with you.

This year, for the 17th Ultra Music Festival, we are truly in awe of what took place. From the brand new music, to the fun-loving adult crowd, to the inspiring visual arts, we only have one thing to say:

Thank you from UMFTV for an AMAZING year at Ultra Music Festival 2015!"
