Lianne La Havas stormed on to the scene last year with a Sound of 2012 nomination and a Mercury prize shout for debut album Is Your Love Big Enough? Part of a new vanguard of female singer-songwriters alongside Jessie Ware and Laura Mvula, a touch of funk and an edge of sass belong to her tracks, with Forget an acerbic love song and Age a witty comment on the dating scene. With Prince and Stevie Wonder united in their acclaim, her Glastonbury debut stands as proof that she is one to watch.
