I definitely think that would be a good addition to the Cherry Classics CD. (Which is awesome)

I also think that something like the trombone excerpt site could be a huge hit.

Such a cd collection would surely be prohibitively expensive, although very handy.

Exactly how many full parts are included on the cherry cd?

There is an online classical music database that has A LOT of recordings. It is often available through college library websites, but I think you can subscribe to it/buy individual tunes. If anyone wants the link I will post it.
