Mariachi Cobre is one of the best known mariachi bands in the United States, performing for millions of visitors at Epcot Center, Disney World in Orland, Florida since 1982. Originally based in Tucson, Arizona, the group was formed by guitarron and guitar player Randy Carrillo, a veteran of the first mariachi group in the U.S., Mariachi Juvenil Los Chanquitos Feos De Tucson. In addition to Carrillo, the original band included his brother, Steve Carillo, on trumpet, guitarron, vihuela and guitar, Mack Ruiz on violin, and Frank Grijalva as the arranger. As of June 2000, Mariachi Cobre has expanded to also include Chris Figueroa (violin), Hector Gama (violin), Miguel Molina (trumpet), Israel Molina (violin), Robert Martinez (vihuela), Antonio Ruiz (violin and viola), Javier Trujillo (guitarra de Golpe), and Mario Trujillo (violin). The group has accompanied a wide range of mariachi and non-mariachi artists including Linda Ronstadt, Lucha Villa, Lola Betran, Ana Gabriel, Guadalupe Pineda, Julio Iglesias, and Vikki Carr. ~ Craig Harris, Rovi
