A question for George and the other folks here. Need help.

I'm looking for recommendations on a particular type of band or album. This is what I'm looking for;

A mixture of the heaviness and power of 1970's 'Black Sabbath', 'Scorpions', and 'Judas Priest' mixed with the progressive, classical, jazzy, and medieval elements of say a band such as 'Renaissance'.

Is there a band or albums that could easily fall into this category? Sails Of Charon by The Scorpions and Genocide by Judas Priest are two of my favorite songs that have a great mixture of early metal combined with those classical, jazzy, and medieval elements I was talking about. I'm looking for a band or bands that have that similiar sound or rather made an album with songs in that sorta vein. Any help you guys can give me would be greatly appreciated. Thanks!

Jay
