Cover art for New Millenium Cyanide Christ lyrics by Meshuggah

Just my take on this song. So through the lyrics Meshuggah is providing a means to perfecting ourselves and to "save a failed humanity". However each of the suggestions of sorts simply removes a characteristic of us humans and in some instances condemns the particular characteristic. I'd say this is especially obvious when they compare the mouth to the "creator of all violence". And with the final verses of the song, Meshuggah tells us to "follow the God of Cyanide", which is the same as taking cyanide. So essentially Meshuggah is condemning humanity and saying the only way to save it is to do away with it entirely, which is of course the dark humor in the song since you can't save something by destroying it. This is backed up in part with the cover of obZen (yes I am aware that this song is not from obZen, but it relates). I saw an interview of Haake on YouTube, in which he explains the cover art of obZen. He points out that the character on the front forms a "666" with his hands and states that it is representative of the nature of Man. While this doesn't specifically explain the meaning of NMCC, you can certainly see some correlations between the two as backed by the previous parts of my comment, and it provides a view on how Meshuggah would (and has) write about Man in their songs.
