Hugh Shrapnel Cantation I - performed by Eric Maltz
"Hugh Shrapnel's Cantation I for piano. The first figure is played by the left hand; after a while the second figure is added with the right hand, then the third figure with the left hand, and so on all through the piece, so that the first note of the new figure coincides with the first note of the existing figure to start with. The tempo is strictly maintained throughout; dynamics are loud and duration between 15 and thirty minutes." (Experimental Music, Michael Nyman, p.8)
In the version the piece is performed on a Moog synthesizer (Moog Sub 37), recorded in one take.
