暗黒の世界
Phillips has provided cover art for music albums including "Starless and Bible Black" by King Crimson (1974), "Another Green World" by Brian Eno (1975), and one of the 16 portraits that form Peter Blake's design for "Face Dances" by The Who (1981). The cover art by Phillips for Dark Star's "Twenty Twenty Sound" (1999) used the same technique as "The Humument", but with the album's lyrics as the source material.
