Track 18 off of Afro Samurai: The Album, “Fury in My Eyes/Revenge” gives a bit of insight into the anime, Afro Samurai. This song, like most of the songs from this soundtrack, was entirely produced by the RZA. This song is played in the final scene of the last episode of Season One.

This song excellently documents Afro’s evolution as character, and his acquisition of the Number One Headband. In this song, the RZA also uses Afro’s quest to relate to some of his own experiences.
