On his official debut album Recess, Skrillex featured everyone from legendary party starter Fatman Scoop to Korean artist G-Dragon. He's been big on collaboration, and over the last six years has worked on a number of side projects, including Jack U with Diplo and Dogblood with Boys Noize. And while many stereotypically paint Skrillex as being a one-trick pony, he's done a lot to help push the EDM sound outside of the American electronic music scene, and a lot of that is through his frequent feature and collaboration work. While some might have been surprised that he got Chance The Rapper and the Social Experiment onto his album, others known he's been on some odd couple shit. Check out the 10 most surprising collaborations in Skrillex's career, so far.
