Mighty Clouds of Joy is an American traditional gospel music quartet. Mighty Clouds of Joy was formed in 1954 and started out in a tradition-based style. Eventually they added soul, R&B, and rock flourishes into their musical mix (one of their early hits was produced by Gamble and Huff) without diluting the essential religious essence of their material. The long-lived group flourished throughout the rest of the 20th century, scoring numerous Grammy Awards and nominations, as well as several hit albums along the way.
