When Diplo released the lineup for his infamous Mad Decent Block Parties on Tuesday, he also revealed another important bit of news: He and Skrillex are now collaborating on a new project called Jack U.

When the highly anticipated lineup was released with the name Jack U alongside the likes of Flosstradamus, Dillon Francis, Riff Raff, Major Lazer and Big Gigantic, it opened up a pretty critical question: Who and what is Jack U? Diplo took to Twitter to address the inquiry: "Jack u ... Means skrillex+diplo together."

Although this musical project is a surprising revelation, the two super DJ/producers are far from strangers. They both recently spoke at the International Music Summit about electronic music and social media, and they debuted a YouTube video channel together earlier this year alongside master turntablist A-Trak.

The YouTube channel POTATO will be a platform for both video and audio premieres, as well as other original content. The DJs even quote MTV's original slogan in their press release: "You'll never look at music the same way again." Since Skrillex, Diplo and A-Trak are each the head of their own record label (OWSLA, Mad Decent and Fool's Gold, respectively), and there is the additional partnership of Jack U to add to their music repertoire, it seems POTATO will not be running out of quality programming anytime soon.

With the wild success and imagination of both producers' other collective musical projects behind them, fans will have to wait until their July 7 debut to find out what Skrillex and Diplo will sound like sharing a stage.

The official Mad Decent Block Parties lineup includes: 3Ball MTY, A Tribe Called Red, Baauer, Big Gigantic, Clockwork, Danny Brown, Destructo, Dillon Francis, Diplo, Dirty South Joe, DJ Dus, DJ Sega, DJ Sliink, ETC! ETC!, Flosstradamus, Grandtheft, Griz, HeRobust, Jack U, Jahan Lennon, Keys N Krates, Kito & Reija Lee, Lunice, Major Lazer, Matt & Kim, Nadastrom, Paul Devro, RiFF RAFF, RL Grime, Rockie Fresh, Samo Sound Boy, Sasha Go Hard, SBTRKT (DJ Set), Skream, Smalltown DJs, Swizzymack, The Partysquad, Thugli, Torro Torro and Zeds Dead.
