De-Loused In The Comatorium  by The Mars Volta

De-Loused In The Comatorium is the iconic debut album of the American band The Mars Volta, released on June 24, 2003. It is considered one of the most important progressive rock albums of the 2000s.

The musical style of the album emerges from a combination of progressive rock and art rock (primarily) and many elements of Latin jazz and psychedelia. De-Loused In The Comatorium is a concept album that tells the story of Cerpin Taxt, a man who falls into a coma after a drug overdose, based on the true story and suicide of artist Julio Venegas. It was produced by Rick Rubin in collaboration with the band's guitarist, Omar Rodríguez-López. It was recorded in 2002-2003 mainly at "The Mansion" in Los Angeles, a mansion rumored to be haunted. Flea from the Red Hot Chili Peppers participated on bass, while John Frusciante participated on the Cicatriz ESP track. The impressive album cover was designed by Storm Thorgerson (known for his collaborations with Pink Floyd), depicting a golden head resembling an egg, placed in a surreal environment.

Despite its experimental style, De-Loused In The Comatorium sold over 500,000 copies worldwide and went gold in the U.S., reaching No. 39 on the American Billboard 200.
