"De-Loused in the Comatorium" is the debut album by the American band The Mars Volta. And what a spectacular debut Cedric Bixler-Zavala and Omar Rodríguez-López delivered. Just as the new wave of progressive rock bands were settling comfortably into a quiet niche, The Mars Volta shook up the prog establishment. No one had charged forward in prog so loudly, so drastically, so fast and so garishly for a long time. "De-Loused in the Comatorium" is a single, full-throttle ride through tempo and key changes, unexpected twists and unheard-of sounds, all delivered with a self-assurance and energy that progressive rock had lost since the days of the legendary King Crimson in the 1970s. The band thus shot straight to the top and made it rather difficult for themselves to top their debut. For ten years, the band constantly reinvented itself, until they split up in the early 2010s and took a decade to reunite. As a debut album, "De-Loused in the Comatorium" is certainly one of the best, most radical and most successful prog albums of the 21st century so far.
