Miley Cyrus played the Glastonbury festival in the U.K. for the first time over the weekend, and amid her hit-packed set, she broke out a surprise cover of Metallica‘s “Nothing Else Matters.” Hear audio of that performance below. Cyrus also played a live rendition of Nine Inch Nails’ “Head Like a Hole,” a song she first covered for an episode of the TV series Black Mirror, titled “Rachel, Jack and Ashley Too,” in which she stars as a fictional pop star Ashley O. In the episode, the NIN classic is retitled “On a Roll” and gets new, upbeat lyrics. Black Mirror series creator Charlie Brooker got Trent Reznor approval to include and rework “Head Like a Hole” for the show. “He wanted to see the script and I got to re-write his lyrics in a chirpy way,” Brooker explained. “I’m not the best lyricist in the world — in the first song she’s singing: ‘I’m stoked on ambition and verve’ instead of ‘You’re gonna get what you deserve.'”
Cyrus’ Glastonbury debut meant a lot to the 26-year-old former Hannah Montana star. “In many ways, this show has changed my fucking life drastically: a lot of hard work, a lot of dedication, and a lot of sacrifice,” Cyrus told the crowd at one point. Previous to both the Nine Inch Nails and Metallica covers, Cyrus performed another notable rock cover: of Temple of the Dog’s “Say Hello 2 Heaven,” at January’s “I Am the Highway: A Tribute to Chris Cornell” concert at the Forum in Los Angeles.
