Benjamin Levin, a.k.a. benny blanco, was just 20 when he graduated from being the dirty-rap beatmaker for Spank Rock to co-producing the slinky title track of Britney Spears' album Circus with mentor Dr. Luke. Since then, Benny has spun his flair for dance grooves and glitzy synths into gold on pop hits like Katy Perry's “Hot n Cold” and slow jams like Rihanna's “Diamonds”.
