Poco: The Songs of Paul Cotton is a compilation album consisting of songs by Paul Cotton of the band Poco, released in 1979.
De-Loused in the Comatorium is the debut studio album by American progressive rock band The Mars Volta, released on June 24, 2003, on Gold Standard Laboratories and Universal Records.
 Based on a short story written by lead singer Cedric Bixler-Zavala and sound manipulation artist Jeremy Michael Ward, the concept album is an hour-long tale of Cerpin Taxt, a man who enters a week-long coma after overdosing on a mixture of morphine and rat poison.
 The story of Cerpin Taxt alludes to the death of El Paso, Texas artist—and Bixler-Zavala's friend—Julio Venegas (1972–1996).
The Bedlam in Goliath is the fourth studio album by American progressive rock band The Mars Volta, released on January 29, 2008 on Gold Standard Laboratories and Universal Motown Records.
 Produced by guitarist and songwriter Omar Rodríguez-López, the album's creation was subject to "bad luck controversy" after an experience with a ouija that Rodriguez-Lopez bought as a gift for vocalist Cedric Bixler-Zavala.
 The album is the first to feature drummer Thomas Pridgen, and the last to include guitarist and sound manipulator Paul Hinojos, wind multi-instrumentalist Adrián Terrazas-González, and keyboardist Isaiah "Ikey" Owens.
Los Dregtones was a band from El Paso, Texas, led by Cedric Bixler-Zavala (vocals/drums), Ralph Jasso (guitar) and Jimmy Hernandez (bass).
 The line-up changed multiple times with Julio Venegas playing bass for a long duration while Hernandez was off at music school at the Atlanta Institute of Music in Atlanta, GA.
 Other members included Luis Prieto (Percussion), Brooks Miller (trumpet), Adam Young (drums), and Andrew McCoi (drums).
 In 1994, they released a demo recorded at Rosewood Studios by Mike Majors (produced by Sparta), titled "Five Song Alibi".
 The style of the album was not unlike what lead singer Cedric Bixler would later perform with The Mars Volta; psychedelic rock, with hints of salsa, reggae, and occasional Led Zeppelin-esque guitar riffs, with punk rock.
 The cover and insert art was drawn by Julio Venegas, which features a six armed serpent women with a third eye and long ugly hair, and a symbol on the end of its tail that would later be used by Cedric and Omar Rodríguez-López on The Mars Volta's stickers, shirts, and other merchandise.
 Guitarist Ralph Jasso would later play bass briefly for The Mars Volta.

Under the Gun is the fourteenth album by the American country rock band Poco.
 Released in July 1980, "Under the Gun" was the followup to Poco's breakout album "Legend".
 "Legend" had been released in November 1978 on ABC Records just prior to that label's being bought out by MCA: in a June 7, 2013 interview with Rockin' Rich Lynch of SoundPress.net Radio Network, veteran Poco member Paul Cotton would state that MCA required that Poco audition prior to being allowed to record for MCA.
 Cotton - "we had to go over to a rehearsal hall and play in front of all the executives" who after hearing Poco perform "Under the Gun", a Paul Cotton composition referencing the pressure attendant on the audition, approved Poco's recording for MCA.
Paul Cotton (born Norman Paul Cotton February 26, 1943 in Fort Rucker, Alabama) is an American guitarist and singer-songwriter, most notable as a member of the band Poco and as the writer of the international hit song from that band, "Heart of the Night".
