The Jimi Hendrix Experience began and finished work on the recording for "Castles Made of Sand" at London's Olympic Sound Studios on October 29, 1967, the penultimate day of recording for Axis: Bold as Love on which the songs "Up from the Skies", "Bold as Love", "One Rainy Wish" and "EXP" were also completed. As with the rest of the album, "Castles Made of Sand" was produced by Chas Chandler and engineered by Eddie Kramer, and was mixed at Olympic on October 31.
Composition and lyrics
Writing the Hendrix biography Jimi Hendrix: Electric Gypsy, commentators Harry Shapiro and Caesar Glebbeek summarise "Castles Made of Sand" as "a sharply observed reflection on life's bitter ironies". Addressing the lyrics of the song, Shapiro and Glebbeek go on to discuss the significance of sand within the track as a metaphor "for the temporary nature of existence, of time slipping away, how nothing can be taken for granted – love, loyalty, family bonds, friendship". It is claimed that "Castles Made of Sand" is one of Hendrix's more obviously biographical songs, said to be written about his uncertain and transitional childhood involving "different homes, different schools, different careers and a mother who was here one minute and gone the next". Hendrix's brother, Leon Hendrix, has commented that the lyrics allude to their father's alcoholism, Leon being taken away so suddenly by Child Protective Services without announcement, and the abusive relationship between their parents. Writer Tom Maginn for AllMusic outlines the lyrical delivery of the song: Musically, "The track begins with overdubbed backwards guitar creeping in, as Hendrix lays down his signature clean guitar sound", drawing comparison with fellow Axis: Bold as Love track "Little Wing". According to Maginnis, "The backwards-recorded guitar... a dreamy atmosphere and the song its distinctive character", with fellow band members Mitch Mitchell and Noel Redding providing a "laid-back groove" with their "mid-tempo drum shuffle" and "concise bass line", respectively. Similarly, Chris Jones of the BBC also notes the "signature backwards guitar" in the song.
Reception
Writing a five-star review of the album for Allmusic, Cub Koda has cited "Castles Made of Sand", along with "Little Wing", "One Rainy Wish" and "Bold as Love", as evidence of Jimi Hendrix's "remarkable growth and depth as a tunesmith, harnessing Curtis Mayfield soul guitar to Dylanesque lyrical imagery and Fuzz Face hyperactivity to produce yet another side to his grand psychedelic musical vision", describing it as a "beautiful, wistful ballad". Speaking about the track specifically, fellow Allmusic commentator Tom Maginnis cites "Castles Made of Sand" as evidence that, in writing material for The Experience's second album, "Hendrix becoming a songwriter of depth, while unafraid to make use of the latest studio technology available to him".
