The Plastic Hearts star teased in an interview earlier this year that she enlisted Sir Elton John, cellist Yo-Yo Ma, Red Hot Chili Peppers drummer Chad Smith and frequent collaborator Watt for a cover of the rock band's 1991 hit "Nothing Else Matters" for an upcoming Metallica covers album. On Tuesday (June 22), Cyrus revealed the other "all-star" in her band: Metallica's very own bassist Robert Trujillo.
"I mean, having Elton John and Metallica and me ... I love when ingredients don't quite fit," she said during a Capital FM interview in January about how the concept might not make sense to fans. "Or it seems like a concoction that no one would ever put together, and you gotta have someone like [the song's producer Andrew] Watt that will take that risk."
