full_context: Document 1: The Definitive Collection (Lou Reed album): The Definitive Collection is Arista's 1999 Lou Reed collection, complete with an appropriately decadent cover photo by Mick Rock from the mid-1970s.
Document 2: Atwater Afternoon: Atwater Afternoon was a limited edition CD released by the band American Music Club and initially sold on the tour to promote their album "The Golden Age". Half of it was a recording of the band rehearsing songs for the tour and the other half was studio recordings of new songs. The initial run of 300 copies came with either blank covers or covers featuring pictures drawn by the band members. Once these had sold out, it was repressed in an edition of 1500 and sold from the band's web site. Two of the original songs on the album were written by members of the band other than Mark Eitzel. Neither has been released elsewhere. The name of the album relates to the area in Los Angeles where the recording took place.
Document 3: Run Run Run (The Velvet Underground song): The song was written on the back of an envelope by Lou Reed while he and the band were on their way to a gig at the Café Bizarre. The song details a number of characters living in New York City, including Teenage Mary, Margarita Passion, Seasick Sarah, and Beardless Harry, all of whom are detailed using or seeking drugs. In addition to mentioning New York scenery such as Union Square and 47th Street, the song makes use of drug terms paired with religious imagery. Two of the four verses directly speak of heroin use, a theme found in the album. In the song, Marguerita Passion tried to sell her soul in order to get "a fix", while Seasick Sarah "turned blue", causing her angels to panic. The song is also well known because of Lou Reed's guitar solo, and its lack of a conventional approach.
Document 4: Metallica: This Monster Lives: The book follows the emotional roller-coaster both he and his film partner Bruce Sinofsky and the band Metallica went through during the creation film. The book takes in the time from Berlinger and Sinofsky's first meeting with Metallica in 1999 to the 2003 Summer Sanitarium Tour. Berlinger and Sinofsky's relationship was at an all time low, exacerbated by Berlinger's decision to direct the disastrous sequel to the Blair Witch. At the start of filming the relationship between the band members, especially between vocalist James Hetfield and drummer Lars Ulrich, is in a similarly perilous position after bassist Jason Newsted quit the band and long standing grudges between the remaining members threaten to escalate past the point of no return.
Document 5: In Through the Out Door: In Through the Out Door is the eighth and final studio album by the English rock band Led Zeppelin.

The song is about the sensations produced by intravenous injection of methamphetamine and features a heavily distorted electric bass outro played by John Cale over a single chord. This bass solo purportedly mimics the throbbing, ear-ringing effects experienced during the methamphetamine "rush."
