MAJOR LAZER, THE DIPLO-HEADED electronic supergroup just threw a hell of a party in Cuba. It was the first concert by a US pop act since Audioslave visited in 2005, and one of very few over the course of the last 50 years. Between 450,000 and half a million people showed up for the concert, which was government-approved, according to the New York Times.

Because of the embargo, Major Lazer “incepted” their music into Cuba ahead of time to build up hype by delivering through a hand-to-hand bootleg service that’s delivered weekly to Cubans. The atmosphere around the concert seemed to mark the start of a new era: “It’s the very first time I’ve seen my generation so happy,” a Cuban told the NYT. Check out the video above to see the massive crowd rocking out during the concert.

Paola Gonzalez, 23, danced to a set by the electronic group @majorlazer in #Havana on Saturday night. The group, led by the DJ and producer @diplo, performed at a few different venues throughout the city over the course of the weekend, which culminated in a free concert attended by an estimated 450,000 to a half-million stylish locals. “I know you’ve been waiting a long time for a party like this,” @diplo called out to the sea of pulsating young Cubans during the concert. With @diplo’s influence reaching new heights, the embargo at its most relaxed in a half-century and travel to Cuba becoming increasingly accessible, @majorlazer began exploring a concert in Havana over a year ago. It was the first show in Cuba by a major pop act from the U.S. since the reinstatement of diplomatic relations between the 2 countries in December 2014.
