I have to say, what could be better than a classical heavy metal album? Having Christopher Lee doing vocals

The dude is amazing, such a unique singing voice.

If you can get your hands on it, Charlemagne:By Blood and the Cross, is a fantastic album. Some great riffs, with Ol Drac singing is worth the money I spent getting it. So far I have only found it on Amazon, but sure you could find it on other sites online. Doubt you will ever see it locally.
