Bourne struck out on her own last year with viral Spotify hit "Wake Me Up".

On "Lava"'s wintry opening, Bourne accessorises a feather-light vocal with childlike chants. The second verse sees a guest appearance from Matthew Hegarty of Matthew and the Atlas take the song in a folk-pop direction. But undulating beats add pop drama, coming together with skittering electronic clicks in a lush chorus: "You're lava," sings Bourne, "I want your fire." The whole thing is a balance of warm and cool tones, offering rich melodies with a dusting of icing-sugar snow.

Tender Central will play St Pancras Old Church on 27 April, followed by festival dates.
