A renowned DJ who has performed across the world, Idris has worked with Jay-Z on the rapper's American Gangster album and Idris himself release his first album in 2014, Idris Elba Presents mi Mandela, and went on to open for Madonna at one of her German gigs.
He has said in the past about making music: "I do it from the heart, I’m not doing it for money — I just enjoy doing it."
Last November he released a single collaboration with Australian indie duo, Lime Cordiale, and that was followed in January with a mini-album, Cordi Elba.
His set isn't the only act to check out at Inside Out - stars of BBC's mockumentary People Just Do Nothing and film, Kurupt FM: Big in Japan, the rap collective will also bring their unique take on British hip hop to Cardiff.
Appearing as their characters from the show and the film, the Kurupt FM crew have appeared at Glastonbury and Reading and Leeds. People Just Do Nothing, which first aired in 2014, follows the lives of MC Grindah, DJ Beats and their friends and their exploits running their pirate drum and bass and UK garage station from a flat in Brentwood.
