Sigma with Armanni Reign

Sigma are a British production duo, Cameron Edwards and Joe Lenzie, who met in Leeds and built their reputation in drum and bass before crossing into mainstream pop. Their early work leaned on liquid rollers and remixes for the dancefloor, and their 2014 single "Nobody to Love", which reworked a Kanye West vocal, reached number one in the UK. "Changing", featuring Paloma Faith, followed to the same position. Later singles brought in guest vocalists across pop and grime, and their live shows typically pair the pair's production with an MC or singer working the front of the stage.
