Joining Jools is US musician and producer George Clinton Parliament Funkadelic, who revolutionized R&B during the 1970s, twisting soul music into funk by adding influences from the likes of Hendrix, Zappa and Sly Stone. The Parliament/Funkadelic machine had huge success over the 70s including their million-selling iconic track One Nation Under A Groove.

Two hugely successful British acts also perform on the show. London folk-rock outfit Mumford & Sons return to debut tracks from their upcoming third studio album Wilder Mind, which sees the band take a turn down a more electric sounding road. And Noel Gallagher's High Flying Birds also return to the show to perform tracks from second album Chasing Yesterday, which topped the chart back in February.

Making her UK TV debut is 27-year-old Mirel Wagner, born in Ethiopia and raised in Finland. Her songs have been described as gloomy blues & folk stripped down to the bone. She performs a track from her second LP When the Cellar Children See the Light of Day, recent winner of the 2014 Nordic Music Prize.

Obaro Ejimiwe, aka south London's Ghostpoet, performs a couple of tracks from his third 'moody alt-rock' album Shedding Skin.

Completing the line-up is Senegalese musician Cheikh Lô, who performs a track from his upcoming album Balbalou. Show less
