Since the early '90s, Pueblo High School's mariachi band has been rocking Tucson. Originally only a dozen students, Mariachi Aztlán de Pueblo High School has grown into a successful establishment of more than 100. This means room for guitar, violin, brass, harp and more. And they're all high schoolers!
