For three hours on Saturday night, The Granada Theatre reverberated with exuberant joy and pulsating rhythm as dancers, musicians, and animated audience members generated a flow of energy throughout the building. The occasion was the 39th annual live performance of local group Danza Folklorica Quetzalcoatl de Santa Barbara, founded and directed by Francisco Espinosa. Titled Lo Mejor del Folklore Mexicano – The bBest of Mexican Folklore – the performance featured 50 skilled and athletic local dancers, ages 5 to 60, accompanied by Banda Maqueos, a 20-piece wind, brass, and percussion youth ensemble from L.A.; and Mariachi Los Camperos de Jesús “Chuy” Guzmán, one of the world’s supreme professional mariachi ensembles. What a night!
