This is a piece for 2 pianos. Its in C, but I make extensive use of tone clusters. The harmony is not functional, its gestural. Piano 1 is a simple melody (D-Bb-A-Bb). For piano 2, I simply hit record and played whatever came to me (with the only the use of gestures, and tonal centre C, planned ahead of time). You can listen to/download the song here
