Bill & Ted Face the Music is a 2020 American science fiction comedy film. It is the third film in the Bill & Ted film series, and the sequel to Bill & Ted's Bogus Journey (1991). Alex Winter, Keanu Reeves, and William Sadler reprise their roles as Bill, Ted, and the Grim Reaper, respectively. In the film, Bill and Ted must write a song to unite humanity before time and space are destroyed. - Rather than focus on the hair metal of the original films, music director Jonathan Leahy involved groups such as Weezer, Mastodon and Lamb of God, who he believed represented the current state of electric guitar. He helped them compose songs for the film, such as Lamb of God's "The Death of Us", used in the future prison scene. As Tosin Abasi was also serving as the "air shredder" for Bill & Ted, Leahy brought in his band, Animals as Leaders, to play on the soundtrack version of the world-saving song.
