John Cage (1912-1992): Two5, for trombone and piano (1991).
James Fulkerson, trombone
Frank Denyer, pianoforte.
The composition uses time brackets. The piano part contains a large amount of seperate pitch events for each time bracket, varying between single tones and dyads. The trombone part is notated in Cage's six-step microtonal system. It also includes glissandos. There are several passages in the work where both musicians remain silent (some of the silences last up to 5 minutes).
