 While rock 'n' roll was fading into lightweight pop and ballads, British rock groups at clubs and local dances, heavily influenced by blues-rock pioneers like Alexis Korner, were starting to play with an intensity and drive seldom found in white American acts.Also significant was the advent of soul music as a major commercial force.Developing out of rhythm and blues with a re-injection of gospel music and pop, led by pioneers like Ray Charles and Sam Cooke from the mid-1950s, by the early 1960s figures like Marvin Gaye, James Brown, Aretha Franklin, Curtis Mayfield and Stevie Wonder were dominating the R&B charts and breaking through into the main pop charts, helping to accelerate their desegregation, while Motown and Stax/Volt Records were becoming major forces in the record industry.
