Hello, Pianists! I am new to this site and forum, so please forgive me if this has been covered already. I'm trying to find the name of the composer of a piece of piano music. I know that at least one recording exists, since I heard it on the radio probably twelve years ago or more. The piece consists of left and right hands playing a fairly straight-forward line in unison. My recollection is that the line resembles an arpeggio, or maybe something that Phillip Glass might compose. This continues throughout the piece, but the trick is that one hand plays one more repetition than the other, in the same time. So, they start together, and they end together. In the middle, there is a progressive shifting of the line played in one hand against the other, and the gradual morphing of the phase is really quite striking.
