Well I used to really like Led Zeppelin, when I was about 15 or so. Does that count?
Well, when I was working at the music department of our library, Led Zeppelin was (and is) in same place with Nightwish, Metallica and Shade Empire, so...
Led Zeppelin heavily influenced the Metal genre of course but they were not strictly a metal band. Was there such a thing as Metal when they were in their heyday?
A lot of their repetoire is not metal. Fr'instnce, take this little ditty:
About as far from Metal as you can get. BTW, any hopeful axe slingers out there should learn this tune. Elias, the guy in the vid will sell you for a buck the full tab and backing track for this tune. The chordal intro and lead line are very simple/easy yet sound great.
