How Long Is “Los diablos azules”?

More than 3,000 miners of Chile’s La Pampa were shot down by the national army during a demonstration in Iquique, a massacre told in Luis Advis’s 1969 cantata Santa María de Iquique. In The Blue Devils, Charlotte Bayer-Broc wanders through one of the ghost mining towns—a remote outpost in the Atacama Desert—interpreting Advis’s lament across eerily abandoned landscapes and industrial vistas. Bayer-Broc upends cinematic convention in a beguiling adaptation that is entirely her own; this medium-length musical is at once personal and political, reverent and burlesque.
