Over the course of a decade-long career, the DJ/producer Diplo’s moved from pop music’s fringes to its very center, where he’s been working with A-listers like Madonna and Snoop Dogg—who look to tap into his talent for transforming eccentric sounds into hit songs. Along the way, he’s managed to keep one foot in the underground, with an indie label called Mad Decent and a cult following on the goofier, less bottle-service-centric end of the EDM scene.
Those fans have helped turn his annual Mad Decent Block Party, which he first started holding outside his house in Philly, into a touring festival that this year hit 22 cities in the U.S. and Canada.
Last week, he launched the first ever Mad Decent Boat Party, a four-day non-stop floating rave on a cruise ship touring the Caribbean. Over 2,700 people made the voyage—including an EW correspondent who was there to document the debauchery. Here’s what we saw.
