On August 3, 2003, The Mars Volta performed at the Summer Sonic Festival in Chiba, Japan, showcasing their unique blend of progressive rock and experimental music. This live recording of "Cicatriz ESP" featured the band at a pivotal point in their career, just after the release of their acclaimed debut album, *De-Loused in the Comatorium*, which came out in 2003. The album was notable not only for its intricate musical compositions but also for its narrative structure, reflecting themes of addiction and the afterlife, inspired by the life of their late friend Julio Venegas. This performance highlighted their energetic live presence and marked the beginning of their rise to prominence in the progressive rock scene. Following this festival, The Mars Volta would continue to evolve their sound, releasing several more ambitious albums and maintaining a reputation for their dynamic and unpredictable live shows.
