Rick Rubin has admitted that he knows “nothing” about music, and that he has no “technical ability” in the studio.

The legendary producer – whose genre-spanning career has included work with JAY-Z, Kanye West, Eminem, LL COOL J, Beastie Boys, Run-DMC and Public Enemy, as well as rock acts like The Red Hot Chili Peppers and Black Sabbath – said in an extensive interview with 60 Minutes that “barely” knows how to make music or even play an instrument.

“Do you play instruments?” Anderson Cooper asked in a clip shared on Twitter. “Barely,” Rubin replied, to which Cooper retorted: “Do you know how to work a soundboard?”

“No. I have no technical ability, and I know nothing about music,” Rubin said, causing Cooper to laugh.
