New Yorks Either / OR performs three of Cages final works, Four3 (scored for one or two pianos, twelve rain sticks, violin or oscillator and silence) and Two6 (for violin and piano), both based on a chance-derived score called Extended Lullaby, based on Erik Saties Vexations, as well as One5 for solo piano. Periodic performances of Cunninghams choreography will illuminate these compositions.
