Physical Graffiti is the sixth studio album by the English rock band Led Zeppelin. Released as a double album on 24 February 1975 in the United States and on 28 February 1975 in the United Kingdom, it was the group's first album to be released under their new label, Swan Song Records. The band wrote and recorded eight new songs for the album in early 1974 at Headley Grange, a country house in Hampshire, which gave them ample time to improvise arrangements and experiment with recording. The total playing time covered just under three sides of an LP, so they decided to expand it into a double album by including seven previously unreleased tracks from the sessions for the band's earlier albums Led Zeppelin III (1970), Led Zeppelin IV (1971) and Houses of the Holy (1973). The album covered a range of styles including hard rock, progressive rock, rock 'n' roll and folk. The album was then mixed over summer 1974 and planned for an end-of-year release; however, its release was delayed because the Peter Corriston–designed die-cut album cover proved difficult to manufacture.

Physical Graffiti was commercially and critically successful upon its release and debuted at number one on album charts in the UK and number three in the United States. It was promoted by a successful US tour and a five-night residency at Earl's Court, London. The album has been reissued on CD several times, including an expansive 40th anniversary edition in 2015. Physical Graffiti was later certified 16× platinum in the United States by the Recording Industry Association of America (RIAA) in 2006, signifying shipments of over eight million copies in the US.

Recording The first attempt by Led Zeppelin to record songs for Physical Graffiti took place in November 1973 at Headley Grange in Hampshire, England, where they had previously recorded their untitled fourth album. The recording equipment consisted of Ronnie Lane's Mobile Studio. Guitarist and producer Jimmy Page and drummer John Bonham recorded an instrumental which was later reworked as "Kashmir" during this visit. However, these sessions quickly came to a halt, and the studio time was turned over to Bad Company, who used it to record songs for their debut album. The press reported that bassist/keyboardist John Paul Jones was ill and unable to record. However, he had become disillusioned with the group and tired of touring, and told manager Peter Grant he was considering quitting. Grant asked him to reconsider and to take the rest of the year off to recuperate.

The group reconvened at Headley Grange in January and February 1974, where they recorded eight tracks engineered by Ron Nevison. Lead singer Robert Plant later referred to these eight tracks as "the belters," including "off-the-wall stuff that turned out really nice." As with previous sessions at Headley Grange, the informal atmosphere allowed the group to improvise and develop material while recording. Sometimes the group would rehearse or record a track several times, discuss what went wrong or what could be improved, and then realise they'd worked out a better alternative arrangement. Bonham was a driving force in the sessions, regularly suggesting ideas and the best ways to play complicated arrangements successfully. This led to him getting a lead songwriting credit on several tracks.

The eight songs extended beyond the length of a conventional album, nearly spanning three sides of an LP, so the group decided to create a double album and add material they'd recorded for previous albums but never issued. This included various jam sessions such as "Boogie with Stu," which Page thought would be unsuitable as a track on a single album. Additional overdubs were laid down, and the final mixing of the album was performed in July 1974 by Keith Harwood at Olympic Studios, London. Page coined the title Physical Graffiti to reflect the physical and written energy that went into producing the set.

The band was also working on a track titled "Swan Song", with instrumental portions recorded during the Physical Graffiti sessions in 1974, with plans to add lyrics. The song was ultimately left off the album, but Page wanted to revisit it, and his 1980s band The Firm recorded a version of it called "Midnight Moonlight". The original track was never released, but can be heard in various bootlegs.

Songs

The album spanned several years of recording and covered a range of musical styles, including hard rock ("Custard Pie", "The Rover", "The Wanton Song", "Sick Again", "Houses of the Holy"), eastern-influenced orchestral rock ("Kashmir"), progressive rock ("In the Light"), driving funk ("Trampled Under Foot"), acoustic rock and roll ("Boogie with Stu", "Black Country Woman"), love ballad ("Ten Years Gone"), blues rock ("In My Time of Dying"), soft rock ("Down by the Seaside"), country rock romp ("Night Flight"), and acoustic guitar instrumental ("Bron-Yr-Aur").

Several tracks from the album became live staples at Led Zeppelin concerts, particularly "In My Time of Dying", "Trampled Under Foot", "Kashmir", "Ten Years Gone", "Black Country Woman", and "Sick Again".

Side one "Custard Pie" was recorded at Headley Grange in early 1974. The first take was played at a faster tempo than the finished version, with various improvised vocals. After a basic run-through, the group then discussed possibilities for rearranging it. Page played the guitar solo through an ARP synthesiser, while Jones overdubbed a Hohner Clavinet part and Plant played harmonica.

"The Rover" was written in 1970 at Bron-Yr-Aur, a cottage near Machynlleth, Wales. It was first recorded at Headley Grange in May 1970 as an acoustic number for Led Zeppelin III. It was reworked as an electric number in 1972 for Houses of the Holy, which formed the basis for the backing track. Page subsequently added guitar overdubs in 1974 with Keith Harwood engineering.

"In My Time of Dying" is based on a traditional song that Bob Dylan recorded on his debut album in 1962. The track was recorded live, with Page later adding further slide guitar overdubs. Bonham led the arrangement and structure, deciding where the stop/start sections should fall and how the group would know when to come back in. The very end of the song features his off-mic cough, causing the rest of the group to break down. Bonham subsequently shouted "That's got to be the one, hasn't it?", feeling it was the best take. It was left on the album to show fans that Led Zeppelin were a working band that took care in their recordings.

Side two "Houses of the Holy" was recorded as the title track for the album of the same name in May 1972 at Olympic Studios with Eddie Kramer engineering. It was left off that album because it was too similar to other tracks, such as "Dancing Days", which were considered better. Unlike some of the other older material on Physical Graffiti, it required no further overdubbing or remixing.

"Trampled Under Foot" developed from a jam session driven by Jones at the Clavinet. The song went through several arrangement changes before reaching the version heard on the album, with the group rehearsing different ideas and arguing over the overall style. Bonham decided the track was too "souly" and rearranged it into a funk style, suggesting that Page should play a guitar riff throughout in place of chords. The lyrics are a series of double entendres around driving and cars. The song quickly became a popular live piece played at many shows from 1975 onwards, and was later revived by Plant for his solo tours. It was released as a single in the US on 2 April (with "Black Country Woman" as the B-side) and was a top 40 hit.

"Kashmir" was an idea from Page and Bonham, and was first attempted as an instrumental demo in late 1973. Plant wrote the lyrics while on holiday in Morocco. Jones played Mellotron on the track and arranged strings and brass parts played by session musicians. The song was one of the album's most critically acclaimed tracks and was played at every gig from 1975 onwards. Page and Plant played it on their 1994 tour, and it was reworked in 1998 by Sean "Puffy" Combs for his single "Come With Me" which featured Page on guitar.

Side three "In the Light" was recorded at Headley Grange in early 1974. It was initially called "In the Morning" and went through several rehearsals and takes to work out a basic structure. Page later added a drone/chant introduction.

"Bron-Yr-Aur" was a solo acoustic piece by Page, named after the cottage where he had composed and arranged much of Led Zeppelin III with Plant. It was recorded at Island Studios in mid-1970. The track was later used as background music in the group's film The Song Remains the Same.

"Down by the Seaside" was originally written as an acoustic track at Bron-Yr-Aur in 1970, and was influenced by Neil Young. The band reworked it as an electric track during sessions for the fourth album the following year. Page and Bonham led the arrangement, changing the tempo from slow to fast and back again.

"Ten Years Gone" was mostly composed by Plant about an old love affair, and was combined with an instrumental piece from Page, featuring overdubbed electric and acoustic guitar parts. When the track was performed live, Jones played a triple-neck guitar featuring mandolin, six- and 12-string guitars to reproduce the various guitar overdubs on the studio recording.

Side four

"Night Flight" was recorded at Headley Grange in 1971 for the fourth album. In addition to the usual bass, Jones plays Hammond organ on the track, and Page plays guitar through a Leslie speaker. Plant wrote the lyrics after reading a news headline entitled "Nuclear Damage Test Threat" and wondered why there seemed to be little peace and love in the world.

"The Wanton Song" was built around a Page guitar riff. Unlike some of the other tracks recorded at the 1974 Headley Grange sessions, it was straightforward to arrange, with the group building the song around the riffs.

"Boogie with Stu" was a jam session with Rolling Stones pianist Ian Stewart based around the Ritchie Valens song "Ooh My Head". It was recorded in 1971 at Headley Grange during the same session that produced "Rock and Roll" for the group's fourth album. It did not credit Valens or Bob Keane, instead crediting Valens' mother. Eventually a lawsuit was filed by Keane, and half of the award went to Valens' mother, although she was not part of the suit.

"Black Country Woman" was recorded in the garden at Stargroves in 1972 for Houses of the Holy, as part of the group's desire to work in "off the wall" locations outside a traditional studio environment. The track was nearly abandoned when an aeroplane cruised overhead, but it was left on the final recording for effect.

Page and Plant wrote "Sick Again" about the 1973 tour and their experience meeting groupies. Bonham's drumming and Page's guitar riffs drove the track. The arrangement had been worked out before recording, and was straightforward to put down on tape.

Unreleased material As Physical Graffiti collected various outtakes from earlier albums, little from the recording sessions was left over and not eventually released. An early arrangement of "Custard Pie", different from the final version, was reworked as "Hots on For Nowhere" on the following album, Presence. A number of other outtakes from earlier album sessions that had not been put on Physical Graffiti were later included on the 1982 album Coda.
