I've just got in from Saddlers Wells after watching Anne Teresa De Keersmaeker's Fase - Four Movements to the Music of Steve Reich. The piece first premiered in 1982 in Brussels and uses Piano Phase, Come Out, Violin Phase and Clapping Music. It's not in my skill set to do the work justice with words but it was like the music was written for the choreography which makes sense as apparently her work often focuses on the relationship between dance and music often with a focus on a specific composer. All pieces were performed as a duo other than Violin Phase with repetitive movements moving in and out of phase making me think it must be incredibly hard to perform. Here's the 'Clapping Song' piece.
