"The Wanton Song" is a song by English rock band Led Zeppelin from their sixth studio album, 1975's Physical Graffiti.
For his guitar solo, Page employed a backwards echo (where the echo is heard before the note), and also put his guitar through a Leslie speaker.
[3] This was a technique Page had himself used as far back as his work with the Yardbirds, and faced serious opposition from audio engineers when he tried it on the earliest Led Zeppelin recordings.
[3] "The Wanton Song" was played live during some of the Led Zeppelin's European and American concerts in 1975, but was discontinued.
[3] On 8 May 1998, Page and Plant performed it on Later... with Jools Holland.
