Performed by two casts of seven dancers, Doubles consists of solos with duets and trios superimposed upon them so that two things are always happening simultaneously. The duality of the choreography, and the fact that two casts are employed to perform the piece, are what gave this work its title. Takehisa Kosugi composed the music by using custom-made light-sensitive oscillators and electronics, varying the sounds by fluctuating the amount of light shone on the oscillators at any given time. Costume design and décor were by Mark Lancaster, which were brightly colored leotards and sweatpants, and a purple backcloth respectively.
