I just found this. I’m about 2 years behind but better late than never. You can get all kinds of brass recordings in MP3 format. Kind of like iTunes for brass geeks:
http://www.worldofbrasstunes.com/
You can also order CDs if you like. Since all of our suitcases were “on the weight limit” for the trip over, our buying is very limited. Brass recordings from this site will be most helpful.
Cheers,
