Rabbath Poucha-Dass?

Anyone know how or where I can find this sheet music?

 

Thanks for the info. Liben didn't have the breakdown of what was contained in " Solo " s book.

Thanks. I sent for it a while ago and was able to familiarize myself with the piece. I was going to perform it at a recital in August but had a conflict so it'll stay on the back burner a while. It really is a far out sounding work.
