Filmmaker Daniela Muñoz Barroso has lost most of her hearing, and can barely hear high frequencies at all. She uses her eyes not only to see, but also to listen. And yet Barroso has developed a fascination for Gladys Esther Linares, aka Mafifa, a female musician who played the bell, a metal percussion instrument prominent in Cuban conga. Mafifa died 40 years ago, at a far-too-young age.
