Editing Physical Graffiti (section)

===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 of its similarity to other tracks such as "Dancing Days", which were felt to be better. Unlike some of the other older material on ''Physical Graffiti'', it required no further overdubbing or remixing.{{sfn|Lewis|1990|p=55}}

"[[Trampled Under Foot]]" developed from a jam session driven by Jones at the Clavinet. The song went through several arrangement changes before arriving at the version heard on the album, with the group rehearsing various different ideas and arguing about 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.{{sfn|Lewis|1990|pp=21–22}} The lyrics are a series of [[double entendres]] around driving and cars. The song quickly became a popular live piece that was played at every live show from 1975 onwards, and was later revived by Plant for his solo tours.{{sfn|Lewis|1990|p=55}} 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.{{sfn|Lewis|1990|p=95}}

"[[Kashmir (song)|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 that were played by session musicians. The song was one of the most critically acclaimed on the album, and was played at every gig from 1975 onwards.{{sfn|Lewis|1990|pp=55–56}} Page and Plant played it on their 1994 tour,{{sfn|Lewis|2010|p=342}} and it was reworked in 1998 by [[Sean Combs|Sean "Puffy" Combs]] for his single "[[Come with Me (Puff Daddy song)|Come With Me]]" which featured Page on guitar.<ref>{{cite book|title=Dancing with the Devil: How Puff Burned the Bad Boys of Hip-hop|first=Mark|last=Curry|page=101|publisher=NewMark Books|year=2009|isbn=978-0-615-27650-2}}</ref>
