Laura Sobrino was first dubbed the "Mariachi Queen" in 1995 by the Los Angeles Times. She has been playing mariachi music for the violin since she was in elementary school. After graduating from Aptos High School in 1972, her career as a semi-professional mariachi began in 1975 while studying for her B.A. in music at the University of California in Santa Cruz. After finishing her studies, she moved to the Los Angeles area to perform professionally, becoming the first woman to play in some of the nation's most prestigious mariachi groups, including the Mariachi Los Galleros de Pedro Rey and the Mariachi Sol de México de José L. Hernández. Laura Sobrino is the former director and lead violinist for the Mariachi Reyna de Los Angeles, and was originally responsible for searching for the female talent in that mariachi. Mrs. Sobrino is currently the musical director and violinist for the new all-female mariachi show group, "Mariachi Mujer 2000."
