The 1960s brought a great increase in public awareness of Magritte's work. Thanks to his "sound knowledge of how to present objects in a manner both suggestive and questioning", his works have been frequently adapted or plagiarized in advertisements, posters, book covers and the like. Examples include album covers such as Beck-Ola by The Jeff Beck Group (reproducing Magritte's The Listening Room), Alan Hull's 1973 album Pipedream which used The Philosopher's Lamp, Jackson Browne's 1974 album Late for the Sky, with artwork inspired by The Empire of Light, Oregon's album Oregon referring to Carte Blanche, the Firesign Theatre's album Just Folks. . . A Firesign Chat based on The Mysteries of the Horizon, and Styx's album The Grand Illusion incorporating an adaptation of the painting The Blank Check. The Nigerian rapper Jesse Jagz's 2014 album Jagz Nation Vol. 2: Royal Niger Company has cover art inspired by Magritte's works. In 2015 the band Punch Brothers used The Lovers as the cover of their album The Phosphorescent Blues.
