METALLICA and Miley's appearance was in celebration of release of the remastered deluxe box set of METALLICA's self-titled fifth album — also known as "The Black Album" — due on September 10 via the band's own Blackened Recordings.

Also included will be a companion set titled "The Metallica Blacklist", which will be packed with covers by major recording artists. Cyrus is among the 53 musicians included in the covers set, which will include her version of "Nothing Else Matters", also featuring Elton John, cellist Yo-Yo Ma, RED HOT CHILI PEPPERS drummer Chad Smith, frequent collaborator Andrew Watt and METALLICA bassist Robert Trujillo.

 

Miley performed her version of "Nothing Else Matters" at the 2019 edition of U.K.'s Glastonbury festival.
