Earlier yesterday the Mad Decent Block Party lineup was revealed alongside some extra chances to grab some tickets. While the lineup was incredibly monumental featuring artists, who, admittedly, probably wouldn’t be seen on the same stage together, there was one that had us scratching our heads.

Who was Jack U? While looking around the internet for information we happened to stumble upon this little tweet from Diplo:


As a surprising addition to an already stellar lineup, it seems that both Skrillex and Diplo will be playing together as Jack U at the Mad Decent Block Parties. It’s has yet to be seen on what type of music they will be playing, but on July 19th in Calgary we’ll have our first taste of what this alliance will sound like. If you haven’t done so, check out the line up here.
