re: Lux Aeterna
The Blue Danube conductor (von Karajan?) had much to do with the power of this version of the Blue Danube, as well. It is like no other performance, but different in very subtle ways. I think Kubrick understood this and his choice was very deliberate. No doubt his selection of the other music was just as well considered. I saw "2001" just a few weeks ago in hi-def TV with a super sound system. It's very hard to believe that film is almost 40 years old.
