During a recent stop on his spoken word tour, Iron Maiden’s Bruce Dickinson revealed his favorite female singer.

During a Q&A portion of the show, Dickinson said, “The one that rolls off the tip of my tongue is Ann Wilson from Heart.”

“Although she didn’t have the kind of — not charisma; notoriety or whatever of somebody like a Janis Joplin, an equally great voice and things like that… she’s just a complete all-arounder,” Dickinson said. “The most amazing voice… Crystalline, she’s a beautiful folk singer, fantastic metal singer with a lovely edge to it, flawless technique.””

Dickinson will be wrapping up his U.S. tour in March in Las Vegas.
