Sometimes the group would rehearse or record a track several times, discuss what went wrong or what could be improved and then realised they had worked out an alternative arrangement for it which was better. As with previous sessions at Headley Grange, the informal atmosphere allowed the group to improvise and develop material while recording. Lead singer Robert Plant later referred to these eight tracks as "the belters", including "off-the-wall stuff that turned out really nice". The group reconvened at Headley Grange in January and February 1974, where they recorded eight tracks engineered by Ron Nevison. Grant asked him to reconsider and take the rest of the year off to recuperate. However, he became disillusioned with the group and fed up with touring, and told manager Peter Grant he was considering quitting. The press reported that bassist/keyboardist John Paul Jones was ill and unable to record.

However, these sessions came to a halt quickly and the studio time was turned over to Bad Company, who used it to record songs for their debut album. Guitarist and producer Jimmy Page and drummer John Bonham recorded an instrumental which was later reworked as " Kashmir" during this visit. The recording equipment consisted of Ronnie Lane's Mobile Studio. 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. 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. The album has been reissued on CD several times, including an expansive 40th anniversary edition in 2015. It was promoted by a successful US tour and a five-night residency at Earl's Court, London. 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 US. 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. The album covered a range of styles including hard rock, progressive rock, rock 'n' roll and folk. The total playing time covered just under three sides of an LP, so they decided to expand it into a double by including previously unreleased tracks from the sessions for the earlier albums Led Zeppelin III, Led Zeppelin IV and Houses of the Holy. 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. It was released as a double album on 24 February 1975 by the group's new record label, Swan Song Records. Physical Graffiti is the sixth studio album by the English rock band Led Zeppelin.
