Career
Career
• Illustration — Roy Estrada (left) with Frank Zappa and The Mothers of Invention (1968) 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.

Grande Mothers
Grande Mothers
In 2002, two years after his release from jail, Estrada joined forces with fellow former Mothers Don Preston and Napoleon Murphy Brock, along with guitarist Ken Rosser and drummer and percussionist Christopher Garcia, to form "The Grande Mothers". They performed at numerous concerts and festivals throughout the United States, Canada and Europe, including Austria, Belgium, Croatia, Czech Republic, Denmark, the UK, Germany, the Netherlands, Italy, Norway and Switzerland. In 2005, guitarist Miroslav Tadić replaced Ken Rosser in the line-up. Robbie "Seahag" Mangano was the guitarist for all of the European Grande Mothers' tours from 2009-2012. Mike Miller and Max Kutner played guitar for the band following. In 2003 Estrada was featured on the album Hamburger Midnight (taking its title from a George/Estrada co-composition on the first Little Feat studio album) on the record label Inkanish Records, on which he collaborated once again with Jimmy Carl Black.
