Rosas is the company of the choreographer and dancer Anne Teresa De Keersmaeker. It was founded in 1983 during the creation of the piece Rosas danst Rosas. Since her debut in 1982 with Fase, Four Movements to the Music of Steve Reich, De Keersmaeker has been engaged in a rigorous exploration and articulation of movement, from its simplest forms to its most complex. The relationship between movement and music is essential to De Keersmaeker’s concept of dance. Rosas has expanded the art of dance as an act of writing movements in space and time, and has over the years explored choreography in partnership with other compositional forces, namely music, geometry, the visual arts, and language. De Keersmaeker’s engagement of these disciplines has involved collaborations with experts—musicians, composers, visual artists, actors, writers—who have at different times been integral participants and performers in Rosas productions.
