I had meant to reply to your post a while back, and running into an article finally prompted me to.
I grew up listening to whatever my parents listened to as I've mentioned before (Beatles, Mexican popular music, classical music, Mexican classic ballads, etc.) At some point I got into Rock music: Queen, The Police (though they sound more like Jazz in their early days), David Bowie, etc. At some point I was all into the hair bands: Cinderella, Ratt, Poison, Motley Crue, etc. I never got into Black Sabbath but I did like Deep Purple. 8th and 9th grade I had some heads in my apartment complex and we rode the buses together, and they got me into Metallica. I loved it. Maybe 10 years later I ran into a school friend whom I hadn't seen in 10 years, and we both remarked how embarrassing it was to have like Twisted Sister. I guess it was right at the time for us being tweens. At that point we were in San Antonio (a much harder rocking town than Austin IMO), Guns-n-Roses and the start of Grunge, I still remember 99.5 KISS ads for Soundgarden at the Sunken Gardens Theater. It's all an evolution in taste.
35 years later or so, and I love the old Black Sabbath. To think of how early they were (I bet most gen-x don't realize how early they were) is just amazing.
I would recommend you re-visit Black Sabbath.
Here's the article that prompted this post:

PS I still think Jethro Tull winning the first Grammy for Heavy Metal over Metallica And Justice For All is a travesty. Fight me.
With that:
