If you don’t believe in extra-terrestrial activity then how do you explain the existence of Rick Rubin? On appearance alone you can see that the man is from a different planet. But it’s his understanding of music that really sets him apart from the human race. Rick Rubin has worked with artists on every spectrum of the music scale; his range stems from The Mars Volta and Rage Against the Machine to The Dixie Chicks and Adele; he even stopped to popularise the hip-hop genre, with Run DMC and The Beastie Boys along the way. He was responsible for saving Johnny Cash from a gospel love-in with his production of the American Recordings. If you’ve seen Johnny Cash’s appearances with Christian extremists during the 80’s you’ll know just how superhuman the achievement was.
