Dressed in formal suits in rich jewel tones and deep black, elaborately embroidered with gold and silver, these mariachi bands had the look and the sound of seasoned professionals.

And they entertained the packed auditorium like professionals.

Six bands from Santa Ana Unified School District campuses participated in the Wednesday night Mariachi Festival, a free community concert held in the Bill Medley Auditorium at Santa Ana High. This was the event’s third year.
