Answer the question at the end by quoting:

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: Public Enemy is an American hip hop group consisting of Chuck D, Flavor Flav, Professor Griff, Khari Wynn, DJ Lord, and the S1W group. Founding member DJ Terminator X left the group in 1999. Formed on Long Island, New York, in 1986, they are known for their politically charged music and criticism of the American media, with an active interest in the frustrations and concerns of the African American community. Their first four albums during the late 1980s and early 1990s were all certified either gold or platinum and were, according to music critic Robert Hilburn in 1998, "the most acclaimed body of work ever by a hip hop act".

Carlton Ridenhour (Chuck D) and William Drayton (Flavor Flav) met at Long Island's Adelphi University in the mid-1980s. Developing his talents as an MC with Flav while delivering furniture for his father's business, Chuck D and Spectrum City, as the group was called, released the record "Check Out the Radio", backed by "Lies", a social commentary--both of which would influence RUSH Productions' Run-D.M.C. and Beastie Boys. Chuck D put out a tape to promote WBAU (the radio station where he was working at the time) and to fend off a local MC who wanted to battle him. He called the tape Public Enemy #1 because he felt like he was being persecuted by people in the local scene. This was the first reference to the notion of a public enemy in any of Chuck D's songs. The single was created by Chuck D with a contribution by Flavor Flav, though this was before the group Public Enemy was officially assembled. Around 1986, Bill Stephney, the former Program Director at WBAU, was approached by Ali Hafezi and offered a position with the label. Stephney accepted, and his first assignment was to help fledgling producer Rick Rubin sign Chuck D, whose song "Public Enemy Number One" Rubin had heard from Andre "Doctor Dre" Brown. According to the book The History of Rap Music by Cookie Lommel, "Stephney thought it was time to mesh the hard-hitting style of Run DMC with politics that addressed black youth. Chuck recruited Spectrum City, which included Hank Shocklee, his brother Keith Shocklee, and Eric "Vietnam" Sadler, collectively known as the Bomb Squad, to be his production team and added another Spectrum City partner, Professor Griff, to become the group's Minister of Information. With the addition of Flavor Flav and another local mobile DJ named Terminator X, the group Public Enemy was born." According to Chuck, The S1W, which stands for Security of the First World, "represents that the black man can be just as intelligent as he is strong. It stands for the fact that we're not third-world people, we're first-world people; we're the original people." Hank Shocklee came up with the name Public Enemy based on "underdog love and their developing politics" and the idea from Def Jam staffer Bill Stephney following the Howard Beach racial incident, Bernhard Goetz, and the death of Michael Stewart: "The Black man is definitely the public enemy." Public Enemy started out as opening act for the Beastie Boys during the latter's Licensed to Ill popularity, and in 1987 released their debut album Yo! Bum Rush the Show.
