I'm a fan (and you should be too) because...Ozzy Osbourne is the father of metal.
This dude was metal before it was popular, waaaaayyyyyy before. He's an amazing singer/song writer, and you gotta admit, he puts on one hell of a show! I don't know how many I can speak for when I say this man's music got me through Jr. High and High School. First time I ever seen him live, I was 15 years old and my father took me to see him in Dallas with During the Black Sabbath Reunion Tour. I remember that night like it was yesterday it's one I'll never forget. I remember Pantera opened for them that night and I was in Metal Heaven. Ozzy has been doing this for a very long time and I wish him long life and health to continue doing it for as long as possible.
