Watch Soul Deep: The Story of Black Popular Music Season 1 Online

The term rhythm and blues was coined by Billboard Magazine journalist Jerry Wexler after he was asked by his editor to find an alternative for the label 'race music'. In a previously unseen BBC interview with Ray Charles, he reveals how his innovations first brought soul to a wider audience. As the black sounds crossed the racial divide, rhythm and blues gave birth to rock 'n' roll – a far more sanitised version of the black sound which was seen to be "too uninhibited, too loose, and too sweaty." Black artists were squeezed out of the mainstream charts by white covers of their songs and Charles looked back to his roots for his inspiration and the creation of his own distinctive sound.
