This past weekend was Mad Decent’s famous Boat Party and among the many performers was Mad Decent frontman himself, Diplo. What many boat-goers weren’t expecting (or maybe they were), was a surprise appearance from Skrillex for an impromptu JACK U set.

One attendee managed to catch about 15 minutes on his phone, and for a phone video uploaded to YouTube, I’ve gotta say the quality is actually pretty decent.
