23. Cattle Decapitation: Humanure

This is a spoof of Pink Floyd's Atom Heart Mother. In general, this band writes songs about what it would be like if humans were to be put in situations cattle have to go through. This idea is as brilliant as its grotesque. In fact it was a little too sick, and not the good 'sick' for some retailers as they refused to carry the album. The cow itself had to removed from the cover to please them, leaving just the barren wasteland. Despite that, kudos go out to the band for fearlessly portraying their beliefs through the music as well as the cover art.
