Many bands, particularly in the developing London club scene, tried to emulate black rhythm and blues performers, resulting in a " rawer " or " grittier " sound than the more popular " beat groups ".

Many helped pioneer psychedelic, and eventually progressive and hard rock, having a major influence of the nature and sound of rock music and meaning that rhythm and blues would be a major component of that sound.
