question

I need some help from people who know more about internet shopping than I do. Where does one go to buy CDs of musicals that are not in English? There are two that I've gotten into:

Elisabeth, about the life of Elisabeth, Empress of Austria-Hungary. A very hot Death is one of the main characters. (in German)
Dracula - Entre l'Amour et la Mort (in French). Take a guess as to what that one's about.

YouTube is very nice for watching clips of the performances, but a full recording would be even better. Any help is appreciated.
