In February 1972, during the height of their popularity, Led Zeppelin performed "Immigrant Song" live at the Sydney Showground. This recording came shortly after the release of their fourth studio album, commonly referred to as "Led Zeppelin IV," which had been released in late 1971. This album featured some of the band's most iconic tracks and marked a peak in their creative evolution, showcasing a diversity of musical styles and more intricate arrangements. The live performance of "Immigrant Song" underscores the band's powerful stage presence and the dynamic energy they brought to their concerts, encapsulating the transition from their earlier, rawer sound to the more polished and grandiose style that would characterize their later shows. Notably, "Immigrant Song" itself incorporates themes of Norse mythology and reflects the band's fascination with epic narratives, a recurring feature of their music during this period.
