IN: The Dark Side of the Moon is the eighth studio album by English rock band Pink Floyd, released on 1 March 1973 by Harvest Records. The album built on ideas explored in earlier recordings and live shows, but lacks the extended instrumental excursions that characterised their earlier work. Its themes explore conflict, greed, the passage of time, and mental illness, the latter partly inspired by the deteriorating mental state of founding member and principal contributor, Syd Barrett. Developed during live performances, an early version was premiered several months before recording began; new material was recorded in two sessions in 1972 and 1973 at Abbey Road in London.

The album was recorded at Abbey Road Studios, in two sessions, between May 1972 and January 1973. The band were assigned staff engineer Alan Parsons, who had worked as assistant tape operator on Atom Heart Mother, and who had also gained experience as a recording engineer on the Beatles' Abbey Road and Let It Be. The recording sessions made use of some of the most advanced studio techniques of the time; the studio was capable of 16-track mixes, which offered a greater degree of flexibility than the eight- or four-track mixes they had previously used, although the band often used so many tracks that to make more space available second-generation copies were made. Beginning on 1 June, the first track to be recorded was "Us and Them", followed six days later by "Money". Waters had created effects loops from recordings of various money-related objects, including coins thrown into a food-mixing bowl taken from his wife's pottery studio, and these were later re-recorded to take advantage of the band's decision to record a quadraphonic mix of the album (Parsons has since expressed dissatisfaction with the result of this mix, attributed to a lack of time and the paucity of available multi-track tape recorders). "Time" and "The Great Gig in the Sky" were the next pieces to be recorded, followed by a two-month break, during which the band spent time with their families and prepared for an upcoming tour of the US. The recording sessions suffered regular interruptions; Waters, a supporter of Arsenal F.C., would often break to see his team compete, and the band would occasionally stop work to watch Monty Python's Flying Circus on the television, leaving Parsons to work on material recorded up to that point. Gilmour has, however, disputed this claim; in an interview in 2003 he said: "We would sometimes watch them but when we were on a roll, we would get on." Returning from the US in January 1973, they recorded "Brain Damage", "Eclipse", "Any Colour You Like" and "On the Run", while fine-tuning the work they had already laid down in the previous sessions. A foursome of female vocalists was assembled to sing on "Brain Damage", "Eclipse" and "Time", and saxophonist Dick Parry was booked to play on "Us and Them" and "Money". With director Adrian Maben, the band also filmed studio footage for Pink Floyd: Live at Pompeii. Once the recording sessions were complete, the band began a tour of Europe.

IN: Marshall Bruce Mathers III (born October 17, 1972), known professionally as Eminem (often stylized as EMIN3M), is an American rapper, songwriter, record producer, record executive, and actor. Eminem is the best-selling artist of the 2000s in the United States. Throughout his career, he has had 10 number-one albums on the Billboard 200 and five number-one singles on the Billboard Hot 100. With 47.4 million albums sold in the US and 220 million records globally, he is among the world's best-selling artists of all time.

In February 2017, Eminem appeared on "No Favors", a track from Big Sean's album I Decided. In the song, Eminem calls the newly elected President Donald Trump a "bitch", and also raps about raping conservative social and political commentator Ann Coulter, who is a Trump supporter, with a variety of foreign objects. Coulter responded to the lyrics, stating, "I think it's unfortunate that the left, from Berkeley to Eminem with his rap songs, has normalized violence against women, as Eminem has done." Eminem participated in the 2017 BET Hip Hop Awards' annual cypher, using his verse, a freestyle rap called "The Storm", to further criticize Trump and the administration for, among other things, Trump's focus on National Football League players' protests during "The Star Spangled Banner" over Hurricane Maria recovery efforts and lack of gun control reform in the wake of the 2017 Las Vegas shooting. Eminem ended the cypher by giving an ultimatum saying that Trump supporters cannot be his fans. The verse received wide praise among other rappers following its release. In October 2017, Eminem appeared on "Revenge", a track from Pink's album Beautiful Trauma. Starting in late October, Eminem and Paul Rosenberg began teasing what fans speculated was the title of a new album titled Revival, in the form of advertisements for a fake medication of the same name. Later in November, the first single "Walk on Water" was released, which featured Beyonce. The song was first performed, by Eminem, at the 2017 MTV Europe Music Awards on November 12, featuring Skylar Grey. He appeared on Saturday Night Live on November 18, performing "Walk on Water", "Stan" and "Love the Way You Lie" with Skylar Grey. On November 28, Dr. Dre posted a video confirming the album's release date as December 15, 2017. On December 8, Eminem released a promotional single titled "Untouchable" which featured a sample from the duo Cheech & Chong. Despite an online leak of the album two days prior, Revival was released as planned on December 15. On January 5, 2018, the second single "River" was released, which featured Ed Sheeran. It became Eminem's eighth consecutive album to top the US Billboard 200 upon release with 197,000 copies sold in its first week. As a result, he became the first musical act to have eight entries in a row debut atop the chart. The album was met with mixed reviews from music critics. In 2018, an extended edition of "Nowhere Fast" with Kehlani and a remix of "Chloraseptic" featuring 2 Chainz and Phresher were released from Revival.
