"Knights of Cydonia" is a song by English rock band Muse and is the closing track on their 2006 album Black Holes and Revelations.

The song's title refers to the Cydonia region of Mars, which gained public attention from the illusion of a rock formation which looked similar to a human face.

The song was described by BBC Radio 1 DJ Annie Mac on 27 October 2006 as "six minutes and seven seconds of pure genius".

[5] The intro, as performed on the live album HAARP, is a citation of the five tone musical phrase from the film Close Encounters of the Third Kind.

The song uses synthesised and live trumpet parts overlaid with vocals from both Matt Bellamy's higher and lower reaches, spanning B3-E5.

[6] The song, taken in entirety, also bears a striking resemblance to George Bellamy's composition "Ridin' the Wind".

The first 2:03 of the song is a guitar solo to the tune of the lyrics, before Bellamy sings "Come ride with me, through the veins of history."

The video was directed by Joseph Kahn, and stars British actor Russ Bain as the protagonist (The Man With No Name), Richard Brake as the antagonist (Sheriff Baron Klaus Rottingham), and Cassandra Bell as the love interest (Princess Shane Kuriyami).

[citation needed] Oakland hip hop group Zion I released a notable remix of the song in 2008.
