On March 6, Major Lazer became one of the first large-scale American acts to perform in Cuba since both countries’ diplomatic ties were restored in 2015. According to a post on Diplo’s Instagram, the free concert at Havana’s Tribuna José Martí drew 400,000 people. “TO THE PEOPLE AND THE COUNTRY OF CUBA THANK YOU. WE HAVE BEEN HUMBLED BY YOUR LOVE,” the group wrote on their Facebook page. Check out a gallery of images from the historic event here.
