How Long Is “90º Doble vertiente”?

"Dealing with the tensions between work and leisure, nature and culture, the industrial fabric and community, these three films demonstrate how the supposed opposition between these pairs gives way to a subtle interweaving that generates an unusually complex portrait of a social group. Open iron pit mines in the Austrian Alps, hydropower stations in the Atlantic-Pyrenees, and other mountainous locations in the Basque Country harbor floating concert stages, helicopter and motorbike TV transmission units, exhausted bike riders and shouting aficionados, enduro racers, rally cars, flying models, and do-it-yourself soap boxes. All of these mechanized bodies in direct contact with landscapes actively transfigure the territory." Anthology Film Archives on the Vázquez/Arrieta films.
