Carouselambra

"Carouselambra" is the fifth song on Led Zeppelin's 1979 album In Through the Out Door. The title refers to the first section of the song that has similarities to carousel music. At more than 10 minutes in length, the song is the second-longest the band recorded in the studio. John Paul Jones' synthesizers dominate the song, with Jimmy Page's guitar playing a supporting role.

==Composition and recording== With its early working title of "The Epic", "Carouselambra" was conceived during the band's rehearsals at Clearwell Castle in May 1978. The song itself is split in three sections. The first section is a fast-paced showcase of Jones on synthesizer (he overdubbed bass guitar or already recorded it as part of the backing track), with Robert Plant's vocals mixed down slightly underneath Jones, the drums of John Bonham and Page's guitar chord progression. The second section is much slower in pace, highlighting Page's use of the Gibson EDS-1275 double-necked guitar, the only time he used that instrument on a Led Zeppelin studio song, while Plant sings some reflective lyrics. The final section returns to an up-tempo beat, with all four band members performing in unison. Page's deep, droning guitar sound was produced with a Gizmotron, a device that creates infinite sustain, unusual harmonics, and allows the guitar to sound like a string section. A Roland GR-500 guitar synthesizer was also used on this track.
