I was wondering if anybody knew how to get a hold of a copy of Muta in Concerto by Rika Ishige. It is a 4 movement work with each movement to be played on a different saxophone, but all by the same player. It appears on the albums Kyo-En X Vol.1 and Sax Expo!!: Blitz Brass. I haven't been able to find it on any usual site or even using google.
Any information would be very helpful. Thank you.
