Plot: Returning to the show are British vocal powerhouse Jessie Ware, who returns with a couple of numbers from her disco-infused fifth studio album That! Feels Good!, and Nottingham duo Sleaford Mods, fresh from a successful North American tour that included a performance at Coachella. They're joined by three artists making their debuts on the show: Dave Okumu & the 7 Generations, led by the prolific and revered producer and performing a collaboration with ESKA, east London's Olivia Dean, making her TV debut with the song Dive from her forthcoming album Messy, and the Waeve, a musical collaboration between Blur's Graham Coxon and vocalist and musician Rose Elinor Dougall, once a member of The Pipettes
