In early 1971, T. Rex was experiencing a significant evolution in their career, transitioning from their earlier folk-rock roots to a more electrifying glam rock sound. The live recording of "Life's A Gas," captured on January 1, 1971, coincided with the peak of this transformation. This performance followed the release of their acclaimed album, "Electric Warrior," which came out later that year and solidified their status in the glam rock genre. Notably, "Electric Warrior" featured the hit single "Get It On," which propelled T. Rex to mainstream success. The band's charismatic frontman, Marc Bolan, was pivotal in creating the glam rock image, characterized by flamboyant fashion and captivating performances, setting the stage for a remarkable era in music history. The energy and style evident in the live performance reflect the band's newfound commercial appeal and Bolan's growing influence during this vibrant period in the early '70s.
