Run-DMC will headline next year's Isle of Wight Festival.
The US hip-hop pioneers will join DJ David Guetta at the top of the bill on the Friday night slot.
Also announced on Wednesday were singer-songwriter George Ezra, indie-pop group Bastille and newly crowned Brits Critics' Choice winner Rag'n'Bone Man.
Run-DMC's Joseph Simmons said the group "absolutely love playing in the UK".
He added: "It's always such a great reception. You guys rock.
"To be given the chance to play such an iconic UK festival is huge and we're really looking forward to it."
Canadian band Arcade Fire will headline Saturday night while British rocker Rod Stewart is to close the festival on Sunday.
Festival promoter John Giddings said: "The Isle of Wight Festival has always been known for its variety in music and this year is no different.
"To have the world's first and most inspiring hip-hop group headlining alongside one of the world's biggest electronic DJs is fantastic.
"Again there's something for everyone. I know the crowds at the festival are going wild for all the acts, not just the headliners."
Isle of Wight Festival 2017 will run between June 8 and June 11.
