on Wolff and Young

I am looking for the following Wolff's pieces on CD:
- Trio (fl, cl, vln)
- Trio I (fl, trp, vc)
- Duo for violins

Do I have any chance of finding them?

About La monte Young:
1) As far as I know the work "Map of 49's Dream The Two Systems of Eleven 
Sets of Galactic lntervals Ornamental Lightyears Tracery" includes his 
famous drift studies. Except from the CD collection "OHM: Early gurus of 
electronic music", can it be found anywhere else on CD (or a bigger excerpt 
of it)?
2) Have his "scores" been published? E.g. I now nothing about the 
"Compositions 1961" series, which is even bigger than the (more well known) 
1960 ones.
