Communion

With their luminous brand of electro-pop, London-based trio Years & Years layer sweetly smooth vocals over bright and heady beats to create what they call "music you can dance and cry to." They are winners of the BBC Sound of 2015 Poll (an honor previously granted to such hitmakers as Sam Smith, Adele, and Ellie Goulding).The single "King" is at Top 40 and is currently at 4m in audience.
