The production duo have teamed up with Paloma Faith for their new single 'Changing', which will be released in the UK on September 14.
The accompanying music video sees the acts head to downtown Miami, with Paloma performing the track in the backstreets of the famous American city.
'Changing' follows Sigma's previous hit 'Nobody to Love', which went to number one in eight countries, including the UK.
Sigma, also known as Cameron Edwards and Joe Lenzie, recently played at Glastonbury and will appear at summer festivals including Global Gathering, Ibiza Rocks and Bestival.
Paloma, meanwhile, released her third studio album A Perfect Contradiction earlier this year, which reached number two in the UK.
