My parents weren't really "into" music, but they did have a bunch of albums that would probably be considered pop. I listened to most of them and liked some stuff. I really liked Marty Robbins (old western singer) and still do. I guess my Dad's influence got me into country when I was a kid. I still don't get that, though there are one or two artists who still blow me away (Emmylou Harris for one). However, he had two Beatles albums on reel-to-reel tape; Hey Jude & Sgt. Pepper's. Yes. It was that long ago. I fell in love with the Beatles at an early age. They were always my favorite band growing up.
When I was in 6th grade or so, some friends of mine and I started listening to KISS. This went on for a year or two. I stopped buying their stuff right when they all came out with solo albums at the same time. That was junior high. Right about then I got two albums for Christmas that I really liked. I got ELO - Out of the Blue and Aerosmith - Get Your Wings. I dug, and still do, the ELO album, but it took me a while to really start liking the Aerosmith album. One day after school I was walking home with somebody - don't remember who - and we ran into this guy who was this amazing drummer from our school. We walked together for a while and ended up hanging out at his house for a while. He played some Rush for us. I really liked it. For my next birthday, my two best friends got me "2112" and "Hemispheres". I was a Rush fan from that day forward.
I remember going to visit the HS as an 8th grader. While we were there, there was a fire alarm and we had to go out behind the school. We ended up by the smoking area which is where all the burnouts hung out (they were the smokers of course). One guy had a great car stereo and was blasting "Running with the Devil" out of it. I really didn't know what to make of it at the time.
Right then Steve Dahl was on the radio with his whole Disco Demolition thing. Everybody was very anti-disco that I knew (I hung out with the burnouts even though I was about as different from them as you could be). The first hard rock album I ever bought was Aerosmith - Live Bootleg. Joe Perry was my idol. That's why I own two red B.C. Rich Bich guitars. I think because I was hanging out with the burnouts that summer before Freshman year, I started to pick up on some of the hard rock stuff. My best friend was a smoker and he started to pick up on it too. We started getting into anything hard rock/heavy metal. We listened to Scorpions, Black Sabbath (Dio), Zepp, Aerosmith, Triumph, April Wine, Y&T, BOC, Ted Nugent, Bad Company, Van Halen, etc..
From there, I never really stopped listening to metal. We were lucky in that we had a string of metal stations in Chicago for a while. That was enough to keep me in metal. My friends and I used to get together on Saturdays and play D&D, drink, smoke pot (I had quit by this time), and listen to The Blaze all day, every Sat.. That's where I was first acquanted with "Rage for Order". I became a huge Queensryche fan. My friend bought me tickets to see Queensryche open for Metallica that year. That got me into Metallica.
When the metal stations died out in Chicago, I kind became musically lost. The only thing that kept me listening to metal was mp3.com. I used to roam that site downloading samples and found lots of great bands that way. Later, I discovered Impulse Music, and used to stop there on the way home from work about every other week. The problem was that I didn't know any of the bands. I was buying mostly older stuff, and trying one or two bands based on the recommendations of the guy working at the store, or bands that I had heard on mp3.com. One day I was in there and came across a little 2"x3" flyer for a festival called ProgPower. I was psyched because it had all these bands I liked. Then I got to the bottom of the flyer and saw that the date was about a week gone. I had missed it. However, I also found a little fanzine called "Lamentations of the Flame Princess" and picked it up. I read the thing cover to cover. Jim is a really good writer. If he ever writes a book, I'll buy it. I tried out some stuff that he recommended and quickly found that my taste differed quite significantly from Jim's. However, I learned to pick up from his reviews what I might like, and what I wouldn't regardless of whether or not he liked it. LotFP played a huge part in me getting into a lot of the newer bands that I'm into now. Of course, that's how I heard about PPIII. Now I have this forum to find out about new music.
That kinda turned into "My Metal History" rather than how I got started listending to metal. Sorry it's so long.
