The American nu metal quartet Mudvayne references one of Crowley's books in their song "Mercy, Severity". On their album The End of All Things to Come, the sentence "Pain of division is nothing, joy of dissolution is everything." rephrases a line from the Liber AL vel Legis: "This is the creation of the world, that the pain of division is as nothing, and the joy of dissolution all." Also, the Thelemic teaching, "Do what thou wilt shall be the whole of the Law" is rephrased in the song "(K)now F(orever)" as "Do what you will, make it the whole of your law."
