Hi, thank you for reading my post. I saw a heavy metal documentary I think it was on VH1 or MTV- I cant remember. It was the most amazing metal doc I ever saw. It went into a lot of detail explaining the history of metal and all of the sub genres like power metal, thrash metal, death metal.... There was an animation of a Heavy Metal family tree sort of graph that showed all the sub genres. I also remember when they were discussing one of the sub genres- they talked a lot about Rush and Geddy Lee. They went on to say that he is a complete innovator and ridiculously smart. Different metal bands were interviewed throughout the entire doc. And Sebastion Bach was interviewed about Geddy Lee. He said he was like the Math Rock genius or something like that. Also when they were discussing Power Metal- they featured Rob Halford and his singing background.. PLEASE LET ME KNOW IF YOU HAVE ANY IDEA WHAT THE NAME OF THE DOC IS. THANK YOU!
