In January 2008, The Mars Volta performed "Wax Simulacra" during a Yahoo! Live Sets recording, a time when they were promoting their album "The Bedlam in Goliath," which was released in January 2008, just weeks before this live performance. This album marked a significant moment in the band's career, showcasing their distinct blend of progressive rock and experimental sounds, as well as their commitment to pushing musical boundaries. "The Bedlam in Goliath" was noted for its intricate compositions and concept-driven lyrics, largely inspired by a Ouija board that led to a series of unsettling experiences for the band. During this period, The Mars Volta was renowned for their electrifying live performances, which often included extended improvisations, and "Wax Simulacra" is a prime example of their innovative approach to live music, filled with energetic transitions and complex arrangements.
