You might also want to check out Rhapsody, Kamelot, Avantasia, and Symphony X. If you don’t mind a little metal, Cradle Of Filth and Dimmu Borgir have both been known to use a fair amount of violins.
DING DING DING!
Ladies and gentlemen, we have a definite winner here. The one I heard that did have vocals creeped me right out (think Exorcist) but otherwise, this is EXACTLY what I was looking for!
And now you’re going to discover that no one else is doing the same thing, so you’re stuck with Therion. Stick to their later releases, cause they used to be just another death metal band. Secret Of The Runes and Deggial are both great albums too.

LifeOnWry: Two groups. Godspeed You! Black Emperor used to be called Godpeed You Black Emperor, but then they decided to change their name to the punctuated style used by myself and others in this thread. I think it is their deliberately obstuse style.
If you like those gropus, check out mùm who are Icelandic and do a similar post rock/classical thing.
