Decades before 2001, I conceived this piece based on the polyrhythm 9:11 and the arithmetic fact that (9/11)^2 = 2/3 (very nearly).  I never realized the piece back in the 1970s when I thought it through, because I didn't have access to the technology that would make it possible.  Lejaron Hiller offered to help!  I never followed up.  So it's been on my to-do list for about half a century, no exaggeration.  

I working on an orchestrated version, but I quite like how this "piano sketch" came out, so I'm planning to release both.

The underlying structure is related to my piece Primetime for two marimbas (which itself was first conceived as a piece for two carillons, and I have never quite given up on the hope of someday hearing it like that.

I know that this is a long piece so....  Listen to it all.  Listen to part of it.  Listen to it all but not in one sitting.  Use it as background music if that suits you.  Dance to it if you feel it.  Whatever works for you.
