Natasha's Waltz

[Gotterdamerung]

This might seem like a dumb question--Norman Blake, of course! However, since I don't actually have the recording (I have it burned from a friend), I'm not sure about the credits. The song sounds more like a Peter Ostroushko song to me (I know that he is on the recording), though I certainly hear the Blake sound/influence--maybe I have it backward.

Any definitive answers?

Thanks
