Inca Roads (song)

"Inca Roads" for the most part explores the stereotypes of aliens encountering the Incan civilization. These themes, like the album cover of One Size Fits All seem to parody the spirituality of many progressive rock albums around the same era. The lyrics "Did a vehicle come from somewhere out there, just to land in the Andes? Was it round and did it have a motor or was it something different?" imply that a UFO is landing in the Andes mountains. As the song progresses, the lyrics become sillier and seem to mock the beginning of the song. An example of this is "...or did someone build a place or leave a space for Chester's thing to land (Chester's thing... on Ruth). Did a booger-bear come from somewhere out there..." The non-serious nature of these lyrics and even the music itself seem to be mocking other progressive rock bands and their possibly forced divine depth.[3][5]

The song starts with dominant vocals, drums, and marimba, but soon features a massive, iconic guitar solo performed by Zappa in late September 1974 at a live performance in Helsinki, Finland. An edited version of this solo recording (and part of the bass and drums accompaniment) was "grafted" onto a performance of the song from August 27, 1974 at KCET in Los Angeles. This combination of performances forms the backbone of the album version from One Size Fits All. Later, George Duke plays an equally complex solo in ⁷
₁₆. In the video of the KCET performance, entitled A Token of His Extreme, Zappa is seen smiling gleefully as Duke plays his solo, as he plays the backup chords. After a short marimba solo, "Inca Roads" reprises its snappy intro. The song ends with the lyrics "On Ruth, on Ruth, that's Ruth!", acknowledging Underwood for her leading on the marimba.[5][6]

In an interview vocalist and keyboard player George Duke said that Zappa pushed for him to sing on "Inca Roads" and that beforehand Duke had no intentions of singing professionally and was only there to play keyboards. He went on to explain how Zappa had bought him a synthesizer (an instrument which Duke had disliked) and told him he could play around with it if he wanted. This led to Duke playing the synth part on "Inca Roads" as well.[7]

Many early LP copies contain a skip during "Inca Roads" at approximately 4:40 into the track (the end of the solo from Helsinki). This error was a manufacturing defect not caught during the test pressing stage. The album was recalled after the mistake was caught, but a significant number had already been sold. The highly complex nature of the music made it difficult to recognize the error without comparing it to the correct version.

In 2018, Prog magazine named "Inca Roads" at hundredth position in their list "The 100 Greatest Prog Songs Of All Time."[8]
