Over the weekend (June 19), Skrillex performed at Barcelona's Sonar Festival, marking his first performance at the festival since he was featured as the event's headliner in 2013. Now that festival's everywhere are being captured and streamed to viewers worldwide, Skrillex's sets are plentiful on YouTube. However, no one is complaining. To see Skrillex live is an experience, but for those who aren't able to attend his shows, you can catch a glimpse at the incredible production and energy that comes with seeing Sonny Moore in action. The latest of these offerings comes from the Sonar Festival, where Skrillex broke out his signature blend of hard-hitting tunes. Check out the performance above.
