US jazz singer songwriter Gregory Porter, who following his debut on the show back in 2011 has gone on to achieve critical and commercial success with his Liquid Spirit LP going Top 10 in the UK, which also won him a Grammy for Best Jazz Vocal. He returns to the show to perform tracks from his follow-up Take Me To The Alley.

Back in September 2015 in a recording studio in London, Mumford & Sons joined up with acclaimed Senegalese musician Baaba Maal and London/Malawi duo The Very Best to record together for a South African release. They followed it up earlier this year with six shows together across South Africa and they will all be reuniting in Maidstone to perform on the show.

Making her UK TV debut is Nantes-born Héloïse Letissier, aka Christine and The Queens. Moving to London after finishing her studies in 2010, Letissier found herself drawn to the performing arts underworld of Soho, where she met the drag queens of Madame JoJo's, who inadvertently helped birth her musical project. She has grown to become a huge mainstream star in her native France, and is known for her energetic and visually arresting live shows, which see her interact with four male dancers and a shadowy four-piece band. She - and they - will be showing off her dance-art-pop sound and style on the show.

From Sunderland and making their Later… debut are Field Music, who are essentially brothers David and Peter Brewis. Over their 11-year history, they have released six albums, and were nominated for the Mercury Prize in 2012. They will be playing a couple of tracks from their most recent LP, Commontime, which saw them crack the UK Top 40 for the first time, along with garnering a raft of glowing reviews.
