A Merry-achi Christmas is a festive holiday concert that pairs Grammy-recognized mariachi ensembles — including Mariachi Sol de México de José Hernández and Mariachi Reyna de Los Angeles — with folklórico dance for a lively blend of traditional mariachi repertoire and seasonal classics. The production takes place at the Cerritos Center for the Performing Arts in Cerritos, California, and is notable for celebrating José Hernández’s long career championing the mariachi art form while presenting orchestral and popular holiday arrangements in a mariachi style.
