I recently heard a song by Celtic Frost (I think), it was called Therion (it was on the computer, so it probably isn't right), but I don't think that's the actual name of the song. It starts off with some high pitched female vocals, pretty fast, like an orchestra. And has like a violin thing. It goes for about 6 and a half minutes and also has the main male singer singing at parts. Can anyone tell me the name of the song?
