Handbags   (The sad, the bad and the ugly. Non-productive stuff here.)

No, unfortunately. I have played the piano part, though now have arthritis in my fingers so not likely to again.

The piece has no time signature, and most of the notes are rather indeterminate: shown as STEMLESS black noteheads, almost all played sostenuto, and each successive measure contains a different number of notes than the preceding measure. So you cannot 'count' time, nor rely upon metronome or a conductor's baton to keep time.

The two players have to really intuitively tune in to each other to share a sense of the timing: you can see in the video, how the pianist needs to frequently cross hands, and holds left hand poised in mid-air to maintain fluidity.
