Those of you who are familiar with such things will know one rarely sees a female mariachi musician. Rarely, but not never: introducing Mariachi Feminil Orgullo Mexicano. The 10-person troupe boasts full string, brass, and rhythm sections, and every member is a woman. Feminine force like this — wrapped in electric blue, floor-length skirted uniforms edged in stunning silver trim — isn’t something you see every day at your favorite restaurante. Established in 2007, the education-minded troupe was the first XX-chromosomed group of its kind in the Bay Area. Since then, it’s been winning over audiences with its plaintive, powerful renditions of Mexican classics and new favorites.
