Alao, as far as music goes, the Iron Man's intro is often called 'Satan's notes'. This is not due to anyone in Black Sabbath being any particular religion, but due to the sound and the affect it had one the people at the time.
Interstingly, that was Toni Iommi, one of the greatest guitarists out there. You could say that he was the godfather of 'Neoclassical Metal'. Also, he was missing a giant chunk of his finger. He wore a self-made prosthetic.
I can probably go on with factoids, so I'll try not to. This is a Linux forum.
I myself (a classical guitarist by training) am a fan. I also fricken' love some Neoclassical Metal. For example, some of Metallica could fit that category. Malmsteen (a jackass by training) is also an amazingly good example.
