full_context: Document 1: Black Country Woman: "Black Country Woman" is the fourteenth song on English rock band Led Zeppelin's 1975 album "Physical Graffiti". It was originally intended to be part of the "Houses of the Holy" album, which had been released two years earlier.
Document 2: Custard Pie: "Custard Pie" is the opening track on the English rock band Led Zeppelin's sixth album, "Physical Graffiti", released in 1975.
Document 3: Led Zeppelin: Led Zeppelin were an English rock band formed in London in 1968. The group consisted of guitarist Jimmy Page, singer Robert Plant, bassist and keyboardist John Paul Jones, and drummer John Bonham. The band's heavy, guitar-driven sound has led them to be cited as one of the progenitors of heavy metal, though their unique style drew from a wide variety of influences, including blues, psychedelia, and folk music.
Document 4: Led Zeppelin IV: The untitled fourth studio album by English rock band Led Zeppelin, commonly known as Led Zeppelin IV, was released on 8 November 1971 by Atlantic Records. Produced by guitarist Jimmy Page, it was recorded between November 1970 and January 1971 at several locations, most prominently the Victorian house Headley Grange.
Document 5: Led Zeppelin (album): Led Zeppelin is the eponymous debut studio album by English rock band Led Zeppelin, released on 12 January 1969 in the United States and on 31 March 1969 in the United Kingdom by Atlantic Records. Featuring integral contributions from each of the group's four members, the album was recorded in October 1968 at Olympic Studios in London and established their fusion style of both blues and rock music. It also attracted a large and devoted following to the band; Zeppelin's take on the emerging hard rock sound endeared them to parts of the counterculture on both sides of the Atlantic Ocean.
Document 6: Jimmy Page: James Patrick Page, {'1': ", '2': ", '3': ", '4': "} (born 9 January 1944) is an English musician, songwriter, and record producer who achieved international success as the guitarist and founder of the rock band Led Zeppelin.
Document 7: Physical Graffiti: Physical Graffiti is the sixth studio album by the English rock band Led Zeppelin, released as a double album on 24 February 1975 by their newly founded imprint label Swan Song Records. The band wrote and recorded eight new songs for the album at Headley Grange, which stretched the total time of the record beyond the typical length of a single LP, so the band decided to make "Physical Graffiti" a double album by including unreleased tracks from earlier recording sessions: one outtake from "Led Zeppelin III," three from "Led Zeppelin IV," and three from "Houses of the Holy", including the unused title track from the latter album.
Document 8: Led Zeppelin discography: The discography of the English rock band Led Zeppelin consists of nine studio albums, four live albums, nine compilation albums, 16 singles and eight music downloads. Formed in London in 1968, the group consisted of guitarist Jimmy Page, singer Robert Plant, bass player John Paul Jones, and drummer John Bonham. The band pioneered the concept of album-oriented rock and often refused to release popular songs as singles. Nevertheless, four of their ten songs that reached the Hot 100 had no mention of the title in the lyrics: "Immigrant Song", "Black Dog", "Over the Hills and Far Away", "D'yer Mak'er". Their debut album, "Led Zeppelin" (1969), released by Atlantic Records, charted at number six on the UK Albums Chart and at number ten on the United States "Billboard" 200. It received several sales certifications, including an 8 times multi-platinum from the Recording Industry Association of America (RIAA) and Diamond from the Music Canada. Led Zeppelin's second studio album, "Led Zeppelin II", recorded when the band were on tour, was released a few months after the first. It reached number one in several countries, including the UK and the US, where it was certified 12 times multi-platinum. The album produced Led Zeppelin's most successful single, "Whole Lotta Love", which peaked at several music charts in the top 10. "Led Zeppelin III" (1970) was a softer, more folk-based effort compared to the hard rock of the band's previous releases. It also peaked at number one in the UK and in the US.
Document 9: Double album: A double album (or double record) is an audio album which spans two units of the primary medium in which it is sold, typically records and compact disc. A double album is usually though not always released as such, because the recording is longer than the capacity of the medium. Recording artists often think of double albums as comprising a single piece artistically; however, there are exceptions such as John Lennon's "Some Time in New York City" and Pink Floyd's "Ummagumma" (both examples of one studio record and one live album packaged together) and OutKast's "Speakerboxxx/The Love Below" (effectively two solo albums, one by each member of the duo). Another example of this approach is "Works Volume 1" by Emerson Lake and Palmer, where side one featured Keith Emerson, side two Greg Lake, side three Carl Palmer, and side four was by the entire group.
Document 10: Coverdale•Page (album): Coverdale•Page is an album by Whitesnake lead vocalist David Coverdale and former Led Zeppelin and London session guitarist Jimmy Page (as Coverdale•Page), released by Geffen Records on 15 March 1993. The album was recorded at Little Mountain Sound Studios in Vancouver, Criteria Studios in Miami, Highbrow Productions in Nevada and Abbey Road Studios, London. Recording commenced in the fall of 1991 and concluded in early 1992. It was produced by Jimmy Page, David Coverdale and Canadian record producer, Mike Fraser.
Document 11: Led Zeppelin II: Led Zeppelin II is the eponymous second studio album by the English rock band Led Zeppelin, released on 22 October 1969 in the United States and on 31 October 1969 in the United Kingdom by Atlantic Records. Recording sessions for the album took place at several locations in both the United Kingdom and North America from January to August 1969. The album's production was credited to the band's lead guitarist and songwriter Jimmy Page, and it also served as Led Zeppelin's first album to utilise the recording techniques of the engineer Eddie Kramer. Incorporating several elements of blues and folk music, "Led Zeppelin II" exhibited the band's evolving musical style of blues-derived material and their guitar riff-based sound. It has been described as the band's heaviest album.
Document 12: If 4: If 4 is the fourth album released by the English jazz rock band If. It was first issued in 1972 and the last album to feature the original recording line-up. Capitol Records, the band's U.S. label, declined to issue this fourth album. Most of the tracks on this album were issued in the U.S. on "Waterfall", in a slightly different form (and new line-up), by Metromedia Records.
Document 13: The Battle of Evermore: "The Battle of Evermore" is a folk duet sung by Robert Plant and Sandy Denny, featured on Led Zeppelin's untitled 1971 album, commonly known as "Led Zeppelin IV". The song's instrumentation features acoustic guitar and mandolin playing.
Document 14: ...And Justice for All (album): …And Justice for All is the fourth studio album by American heavy metal band Metallica, released on August 25, 1988, by Elektra Records. It was the band's first studio album to feature bassist Jason Newsted after the death of Cliff Burton in 1986. "…And Justice for All" is musically progressive, with long and complex songs, fast tempos, and few verse-chorus structures. The album is noted for its sterile production, which producer Flemming Rasmussen attributed to his absence during the mixing process. The lyrics feature themes of political and legal injustice seen through the prisms of censorship, war, and nuclear brinkmanship.
Document 15: Kashmir (song): "Kashmir" is a song by the English rock band Led Zeppelin. Included on their sixth album "Physical Graffiti" (1975), it was written by Jimmy Page and Robert Plant (with contributions from John Bonham) over a period of three years with lyrics dating to 1973. The song became a concert staple, performed by the band at almost every concert after its release. The song has been described as one of Led Zeppelin's two most overtly progressive epics.
