AC Black formed in the late 90's and signed to Motown Records identical twins Alvin and Calvin Waters, Doug Grigsby and Doug Knight was one of the last self-contained R&B groups, along with Mint Condition and Tony! Tony! Tony! They went on to work with Micheal Jackson, Robbie Williams, Back Street Boys, Ne-Yo, Sean Piddy Combs, Teena Marie, Peabo Bryson etc. Now they are back with a real sound of pure Soul for the new single entitled Crazy Blue.
