Up the Coast in the Golden City, the San Francisco Symphony is celebrating Mexico’s carnavalesque Day of the Dead with a screening of the Pixar hit Coco, accompanied by the live orchestra. Fun, sure. But Gustavo (“The Dude”) Dudamel is diving deeper. His very grown-up fiesta showcases Latin American instrumental and choral extravaganzas. In Yanga (2019), Gabriela Ortiz keeps pulses racing with bursts of polyrhythmic African percussion. The piece, she says, “speaks to the greatness of humanity when in search of equality and the universal right to enjoy freedom to the fullest.” Heitor Villa-Lobos is heard from in Chôros No. 10, “Rasga o Coração,” inspired by the sizzling street musicians of Brazil. And from Mexico proper, there’s the film score La Noche de los Mayas, by Carlos Revueltas. Film historians wrinkle their noses at the tacky movie, but the score—part heavy metal, part pure spirit, all Technicolor in sound—has had a remarkable afterlife. —Matthew Gurewitsch
