Metal? Yippee did it to me - started with Queensryche when we started dating.
My parents, unlike Yip's are VERY into music. I grew up around a LOT of music. My Dad is a guitar player and writer of his own songs. I grew up totally hooked on the 50's and 60's tunes (Solid Gold Saturday night every week) and my Dad was always into great 70's rock music (Styx, etc) and he's a HUGE Pink Floyd Fan. We went to summerfest every single year in Milwaukee saw Moody Blues and Beach Boys 300 times - Rod Stewart, etc etc etc
My Dad worked in a music shop when I was little. He always had top of the line stereo equipment. I remember in their last house, he was the first person any of my friends knew with speakers wired into the walls of the house so we could have the stereo playing in every room
Oh wait, what was the question again? Metal, oh yeah, Yippee did it. I think the first Iron Maiden concert he took me to really turned me.
