Absolutely wonderful scary CD's

Do you know about Baba Yaga? No? Then, my friend, you are *not* well-versed in fairy tales or multicultural stories! Baba Yaga is renowned! She is the infamous Russan folk tale witch who lives in a house on chicken legs, that turns around and around. She flies through air in a mortar and pestle and ... eats children (ahem. might want to gloss over that aspect of it.) I just found a really neat bunch of CD's by an exceptionally talented troupe who sing their way through a series of Baba Yaga stories, including Firebird. Really cool.
