In January 1977, T. Rex was amidst a significant phase in their career marked by a shift in their musical direction and public perception. The live recording of "Dandy In The Underworld" captures the band during a time shortly after the release of their album of the same name, which debuted in 1977 and was one of their final studio albums. This period saw T. Rex moving away from the glam rock sound that catapulted them to fame in the early 1970s, experimenting with different styles that reflected the changing music landscape. Interestingly, Marc Bolan, the band's iconic frontman, faced increasing challenges as the glam rock genre waned in popularity. The performance shows Bolan's charismatic stage presence, which remained a hallmark of T. Rex, while also highlighting the passionate fanbase that the group maintained despite the cultural shifts in music at the time.
