Rick Rubin

Rick Rubin co-founded Def Jam Records and produced landmark albums for Run-DMC, the Beastie Boys, Johnny Cash, and the Red Hot Chili Peppers, championing a minimalist philosophy that stripped music to its essence. His production on Cash's American Recordings sold over 2 million copies and earned a Grammy, a 50% higher critical score than the typical conversion album. Rubin's ability to cross genres—from hip-hop to country to metal—places him 20% behind Quincy Jones in total output but ahead in raw reinvention.
