Led Zeppelin III is the third studio album by the English rock band Led Zeppelin, released in 5 October 1970. As with the prior album, the band eschewed the use of guest musicians, with all music performed by band members Robert Plant (vocals), Jimmy Page (guitars), John Paul Jones (bass, keyboards), and John Bonham (drums). The range of instruments played by the band was greatly enhanced on this album, with Jones especially emerging as a talented multi-instrumentalist, playing a wide range of keyboard and stringed instruments, including various synthesizers, mandolin and double bass, in addition to his usual bass guitar. As with prior albums, Page served as producer on the album, with mixing done by Andy Johns and Terry Manning. The album showed a progression from straightforward rock towards folk and acoustic music. While hard rock influences were still present, such as on “Immigrant Song”, acoustic-based songs such as “Gallows Pole” and “That’s the Way” showed Led Zeppelin were capable of playing different styles successfully.
Many of these are described as work-in-progress or alternate mixes made during the original production rather than new remixes generated to highlight discarded recording elements.
