Soul wasn't just about the southern states and Detroit either. Chicago followed up on its influence on electric blues with its fair share of soul successes. One of the greatest exponents was Curtis Mayfield, who added his own distinctive social consciousness to the soul music movement. The Chess label also followed its blues and R&B hits with a range of soul music successes, including material from the very wonderful Dells and superb stuff from the likes of Mitty Callier, Theola Kilgore and Fontella Bass. And in New Orleans, you could listen to an altogether different sound - funky, expressive and full of the undeniably feel good factor of Louisiana. And the music continued to evolve, with the Philadelphia sound of Gamble and Huff virtually reinventing the genre in the 70s through the music of groups such as the O'Jays, Harold Melvin and the Bluenotes and the underrated Spinners.
