A collaborative track between Major Lazer and Toronto trap producer Grandtheft called “Number One” has just popped up on SoundCloud, from the former’s “LAZER VAULT.”

The twitchy, electro dancehall track gives a festival-friendly facelift to Johnny Osbourne’s 1985 reggae hit “Buddy Bye.” Diplo & Co. previously sampled the Jamaican musician’s “Mr. Marshall” on their 2012 song “Jah No Partial” with Flux Pavilion.

Major Lazer made headlines earlier this month by playing for nearly half a million people in Havana, Cuba. The group became one of the first US acts to perform in Cuba since the nations normalized diplomatic ties.

Listen to the track below.
