Bill & Ted Face The Music is less than two weeks away from being released, and one very notable cameo can be expected in the film.

Per Rolling Stone, Dave Grohl makes an appearance in the film, as does Arcade Fire frontman Win Butler. There’s no word yet on whether Grohl and Butler will be playing themselves or possibly portraying other notable historical figures, which could be pretty funny.

Bill & Ted Face the Music comes out in select theaters and on-demand on August 28. That same day, the film’s soundtrack also comes out and features Weezer, Mastodon, Lamb of God, Cold War Kids and more. The Bill & Ted Face the Music soundtrack is currently available for pre-order/pre-save here.
