Question: What other album covers did Storm Thorgerson depict? Passage:The record builds on ideas explored in Pink Floyd's earlier recordings and performances, while omitting the extended instrumentals that characterised their earlier work. A concept album, its themes explore conflict, greed, time, death, and mental illness, the latter partly inspired by the deteriorating health of founding member Syd Barrett, who departed the group in 1968. The group used recording techniques such as multitrack recording, tape loops, and analogue synthesisers. Snippets from interviews with the band's road crew, as well as philosophical quotations, were also used. Engineer Alan Parsons was responsible for many sonic aspects and the recruitment of singer Clare Torry, who appears on "The Great Gig in the Sky". The sleeve, which depicts a prism spectrum, was designed by Storm Thorgerson, following keyboardist Richard Wright's request for a "simple and bold" design, representing the band's lighting and the record's themes. The album was promoted with two singles: "Money" and "Us and Them".

Question: What album featured the Ashlee Simpson song that was in the top ten most popular songs on the iTunes store with A Public Affair? Passage:"A Public Affair" was released as the album's lead single on June 29, 2006. The song received mixed reviews from critics, with many criticizing its close similarity with "Holiday". The song also channeled Janet Jackson with its "breathy vocals, cheery, almost sickeningly sweet melody", and "mid-song giggle". The music video was shot on June 23, 2006 and the late evening of June 24, 2006 at the Moonlight Rollerway in Glendale, California. It features appearances by Christina Applegate, Christina Milian, Eva Longoria, Maria Menounos, Andy Dick and Ryan Seacrest. On July 19, Simpson visited Total Request Live to world premiere the video. In the chart Billboard Hot Videoclip Tracks peaked at the number 5. The single debuted at number thirty-nine on the US Billboard Hot 100 chart, Simpson's second highest debut after "These Boots Are Made for Walkin'". It had previously debuted at number twenty on Billboard's Bubbling Under Hot 100 Singles chart, which represents the twenty-five singles below the Hot 100's number 100 position that have not yet appeared on the Hot 100. Digital download sales were moderate until the release of the single's music video. In late July "A Public Affair" joined Ashlee Simpson's song "Invisible" in the top ten on the US iTunes Store's list of most popular songs, the first time in iTunes history that two siblings had different songs in the top ten. The song peaked in its fifth week on the Hot 100.
