In the ‘70s, Peter Gabriel broke with prog rock's clean vocal style, adopting the bluesy timbre of American singers like Otis Redding, Nina Simone and Robert Johnson—whose “Hell Hound On My Trail” echoes faintly in Genesis' “One Eyed Hound”. As a solo artist, he fed off the energy of terse New Wavers like Talking Heads and African griots such as Youssou N'Dour, an eventual collaborator.
