Mariachi Vargas de Tecalitlan and Chicago Symphony A Mariachi Weekend in Chicago Kaylee Bucio to open the show! Kaylee Bucio along with the kids from the Chicago Mariachi Project accomplished something that night that many of us dream of. They stood on one of the world’s greatest stages to share their passion while performing the music they love for thousands of people. It might be as simple as signing up to a community mariachi program, or as hard as proving yourself in a National Vocal Competition where the odds are stacked against you. Nonetheless if you do it with passion you will get there regardless.
