"[[Misty Mountain Hop]]" was written at Headley Grange and featured Jones playing electric piano.{{sfn|Lewis|1990|p=52}} Plant wrote the lyrics about dealing with the clash between students and police over drug possession.

"[[Four Sticks]]" took its title from Bonham playing the drum pattern that runs throughout the song with four drum sticks, and Jones played analog synth. The track was more difficult to record than the other material on the album, requiring numerous takes.{{sfn|Lewis|1990|p=52}} It was played live occasionally in early 1971.<ref>{{Cite web |title=K.

"[[Going to California]]" was a quiet acoustic number. It was written by Page and Plant about Californian earthquakes, and trying to find the perfect woman. The music was inspired by [[Joni Mitchell]], of whom both Plant and Page were fans. The track was originally titled "Guide To California"; the final title came from the trip to Los Angeles to mix the album.{{sfn|Lewis|1990|p=52}}{{sfn|Lewis|2010|p=78}}

"[[When the Levee Breaks#Led Zeppelin version|When the Levee Breaks]]" came from a blues song recorded by [[Memphis Minnie]] and [[Kansas Joe McCoy]] in 1929. The track opened with Bonham's heavy unaccompanied drumming, which was recorded in the lobby of Headley Grange using two [[Beyerdynamic]] M 160 microphones suspended above a flight of stairs; output from these were passed to a [[limiter]]. A [[Binson|Binson Echorec]], a [[Delay (audio effect)|delay]] [[effects unit]], was also used.<ref>{{cite web | url =https://www.musicradar.com/news/drums/andy-johns-on-the-secrets-behind-the-led-zeppelin-iv-sessions-586533 | title =Andy Johns on the secrets behind the Led Zeppelin IV sessions | last =Welch | first =Chris | date =31 October 2013 | website =MusicRadar | publisher =Future Publishing | access-date =28 October 2018 | archive-date =4 November 2018 | archive-url =https://web.archive.org/web/20181104074323/https://www.musicradar.com/news/drums/andy-johns-on-the-secrets-behind-the-led-zeppelin-iv-sessions-586533 | url-status =live }}</ref> Page recalled he had tried to record the track at early sessions but it had sounded flat. The unusual locations around the lobby gave the ideal ambience for the drum sound.{{sfn|Lewis|2010|p=84}} This [[Break (music)|introduction]] was later extensively sampled in [[hip hop]] music during the 1980s.{{sfn|Lewis|1990|p=52}} Page and Plant played the song on their 1995 tour promoting ''[[No Quarter: Jimmy Page and Robert Plant Unledded]]''.{{sfn|Lewis|2010|p=103}}
