Question: How many years after Wish You Were Here was released was The Wall released? Passage:Storm Thorgerson, who had done the majority of album covers for Pink Floyd, did the Echoes art which features recursive windows in an infinite regression as a nod to his own cover for 1969's Ummagumma, and the objects on each landscape refer to the Pink Floyd discography. For instance, there's the man on fire from Wish You Were Here, another wearing the Delicate Sound of Thunder lightbulb suit, dolls of the Atom Heart Mother cow and the Animals pig, a bike and both a brick wall and the hammers from The Wall. Eventually Thorgerson opted to make two images, with another used for the back cover. To create the idea on a photograph, various walls - which had varied measurements and angles to ensure that "nothing seemed to fit other than by eye through the lens." - were built and put in a country landscape in Sussex. Actors, props and fittings were set in and between those walls. The original design was one of two sketches submitted for Dream Theater's 1997 album Falling into Infinity, with the original being framed and hanging in the home of former Dream Theater drummer Mike Portnoy and is pointed out by Portnoy in his Hudson Music instructional drum DVD In Constant Motion.

Question: How much money was made at the box office by the 1997 David Lynch movie that Mason contributed 2 songs to? Passage:Neil Strauss, a rock critic and reporter for The New York Times, met Marilyn Manson through his work for Spin and Rolling Stone. Strauss initially perceived Manson as a "phony" who had gotten on the gothic rock bandwagon very late; he later came to see Manson as a "really interesting, really intelligent artist" with many talents. He went to talk to Manson at a Holiday Inn in Fort Lauderdale, Florida. Manson asked Strauss to join him in a hot tub, commenting "This is going to be an important piece of press." Strauss wrote a cover story about Manson for Rolling Stone, which in the view of the Chicago Reader Jim DeRogatis "legitimized Manson's emergence as one of the most notorious entertainers of the 90s and an enthusiastic bogeyman for the right". Following the publication of the article, Strauss became Manson's business partner. Later, Manson and Strauss got a deal to write the singer's autobiography for ReganBooks, an imprint of HarperCollins founded by Judith Regan, who was behind Howard Stern's Private Parts (1997). The autobiography shares its title with the Marilyn Manson song "Long Hard Road Out of Hell" (1997) and features an introduction written by film director David Lynch; Manson had previously contributed two songs to the soundtrack of Lynch's film Lost Highway (1997) and would later collaborate with the director on a coffee table book titled Genealogies of Pain (2011).
