I got my first exposure to zeppelin and black sabbath as a little kid. I can't remember my age I think I was 8 or 9.
My most memorable moment was when I brought home my Seventh son of a Seventh son album. I was already a maiden fan by then but that one I so adored more then any at the time, I was 12 or 13 I think. My memory could be fogging up on the exact date.
The other most memorable. I've said it before but I forgot to mention the other cassette I got with it. I got my first Sanctuary tape on a whim because I was board and wanted to listen to something new. In the tape store and just grabbed it without ever listening to it, and never heard of them before. I also grabbed my first Enya tape with that one. I had no idea what that was going to sound like, and knew damn well that Enya wasn't even metal. Well, I loved both of them and Sanctuary was right up there next to Maiden for me. I think that was in 89. Lets just say that I had a gut feeling that I would love them both.
