Roy Estrada (also known as "Roy Ralph Moleman Guacamole Guadalupe Hidalgo Estrada" and "Orejón"; born April 17, 1943) is an American former musician and convicted sex offender. He is best known for his bass guitar work with Frank Zappa and the Mothers of Invention; for having been a founding member of Little Feat, playing on their first two studio albums; and for being a member of Captain Beefheart's the Magic Band. Estrada is currently incarcerated in the Texas State Prison System. He was convicted for sex offenses, first having been convicted of child sex abuse in 1994 and serving six years' imprisonment, then pleading guilty to abuse of a young relative in 2012. He will not be eligible for release until 2036, at which time he will be 93 years old. Career With drummer Jimmy Carl Black and vocalist Ray Collins, Estrada was an original member of Frank Zappa's Mothers of Invention. Previously, Estrada had been a founding member of the Soul Giants, the band from which the Mothers of Invention was formed. In addition to playing bass guitar, Estrada sang vocals—often in a falsetto in Zappa's arrangement of doo-wop harmonies. On the 1969 album studio Uncle Meat, for example, he was credited with bass guitar and "Pachuco falsetto." Prior to the Soul Giants, Estrada fronted a band called Roy Estrada and the Rocketeers. The group released at least one single on the King label, "Jungle Dreams (Part 1)" backed with "Jungle Dreams (Part 2)". In addition to his work with Zappa, Estrada formed Little Feat with Lowell George, Richie Hayward and Bill Payne in 1969, playing bass and singing backing vocals on their first two studio albums before quitting in 1972 to join Captain Beefheart's Magic Band. Beefheart gave him the nickname "Orejón" ('big ears'). Estrada returned to Zappa's band for a tour that ran from September 1975 to March 1976. The posthumous Zappa archival release Joe's Camouflage featured pre-tour rehearsal recordings, while recordings from the tour appeared on the archival releases FZ:OZ, Joe's Menage and Zappa ’75: Zagreb/Ljubljana. Zappa's 1976 studio album Zoot Allures included one track from the tour as well as studio recordings with Estrada on backing vocals. Estrada later provided vocals and acting for Zappa's 1979 film Baby Snakes, and vocal work for the 1980s Zappa studio albums Ship Arriving Too Late to Save a Drowning Witch, The Man from Utopia and Them or Us.
