A century and a half has passed since Charles Darwin’s «On the Origin of Species,» a publication that changed people’s perception of themselves and their world forever. Now Hotel Pro Forma, an international collective of artists, provides its own unique take on the evolution of species, along with the development of human nature and behavior. The production, going on stage at the Pallas Theater tomorrow and Saturday, is directed by Ralf Richardt Strobech and Kirsten Dehlholm, and is inspired by Darwin’s journeys aboard the Beagle as a young man. Over the course of five years, Darwin traveled the world, and his letters and observations have become a source of inspiration for this large-scale visual production. «Tomorrow, in a Year,» is an electro-opera based on Darwin’s life and scientific theories, in which the English naturalist’s visual stimuli are mixed with the avant-garde music of the Swedish brother-and-sister electronica group the Knife in order to to portray Darwin, time and nature. Six dancers re-enact the substance of life in a hip-hop-inspired choreography by Hiroaki Umeda, while audiences will rediscover the world through new technologies in light and sound. Based in Denmark, Hotel Pro Forma develops each of its productions by exploring space and content by mixing architecture, tradition and history. At the Pallas Theater (5 Voukourestiou, tel 210.321.3100) tomorrow and Saturday.
