In reply to John Phillips request for available CD's of Conlon
Nancarrows' work, there is a 5 CD set with a 140 page booklet
available as listed below:

 Conlon Nancarrow - Studies for Player Piano
Wergo  # wer 6907 2   Barcode No. 4 010228 690729

Wergo is a division of Schott Music & Media in Mainz, Germany

I special ordered my set through Barnes & Noble here in the states.
It took awhile for them to find it in their computer, but they finally
found it.  It may be possible to order the same from their web site.
Cost is approx. $65 for the set, and well worth the money.
