10 Things You Didn't Know About Hot 100 Fest's 2017 Dance Headliners

Here are some fun facts about Major Lazer, Zedd and Marshmello.

With less than 24 hours to go before the Billboard 2017 Hot 100 Festival hits Jones Beach in New York, it's time to brush up on our knowledge of the fest's dance headliners. This year, that means getting the facts straight on Major Lazer, Zedd and Marshmello.

In advance of their hotly anticipated sets on Aug. 19 and 20, we've rounded up the 10 things you might not know (but should) about these electronic hitmakers. Read on for all the deets below, from how Major Lazer made musical and political history to Zedd's first gig in a metalcore band.

Major Lazer

In March, Major Lazer became the second U.S. act to play a major concert in Cuba in the more than 50 years (Audioslave came first in 2005), and the first since the restoration of diplomatic ties between Washington and Havana in 2014. It wasn't easy: the gig came only after 14 months of negotiations, and Major Lazer weathered a $150,000 financial hit to put on the show.

Major Lazer got its start nearly a decade ago, after Diplo and U.K. beatmaker Switch produced M.I.A.'s breakthrough Arular and follow-up, Kala. They decided to round up dancehall stars to jump on the project's leftover beats, involving Jillionaire early on. Walshy Fire joined in 2012 from the dancehall crew Black Chiney, after Switch left in 2011.

Zedd

Zedd first moved to the United States to work on Lady Gaga's Artpop LP. Gaga paid for his first pad -- a cramped Santa Monica apartment with walls so thin, he could hear his neighbor's cellphone vibrating nextdoor.

Zedd was drummer for his brother's metalcore band Dioramic from age 12 to 20, and the group would sometimes skip class to tour in Germany.

The first album Zedd ever purchased was Daft Punk's Discovery.

Zedd, born Anton Zaslavski, got what would become his stage moniker in middle school, when he sat next to a friend with the same first name. To avoid confusion, the boys were referred to by the first letters of their last name. For Zaslavski, that meant going by the European "zed."

Marshmello

Marshmello's first No. 1 on the Beatport charts was actually not a dance or electronic chart. His remix of 'Where Are U Now" by Jack Ü landed the No. 1 spot on the Beatport's Hip-Hop chart.

Marshmello's standout single "Alone" went Gold on May 26, 2017, according to RIAA. 

The DJ's first helmet weighed in at a whopping 13 pounds, according to his management.

This August, Marshmello's jam-packed schedule landed him in nine countries within the span of just one week. He made time for Hot 100 Fest, though, so check him out along with Zedd, Major Lazer and so many more!
