In a 2018 book about classic rock, Steven Hyden recalls concluding, in his teens, that "The Dark Side of the Moon" and "Led Zeppelin IV" were the two greatest albums of the genre, vision quests "encompass the twin poles of teenage desire". They had similarities, in that both album's cover and internal artwork eschew pictures of the bands in favor of "inscrutable iconography without any tangible meaning (which always seemed to give the music packaged inside "more" meaning)". But whereas Led Zeppelin had looked outward, toward "conquering the world" and was known at the time for its outrageous sexual antics while on tour, Pink Floyd looked inward, toward "overcoming your own hang-ups" and seemed so sedate and boring that, Hyden commented, the scene in "Live at Pompeii" where they take a lunch break at the studio might well have been the most interesting part of recording "The Dark Side of the Moon".
