Led Zeppelin - without a doubt!
Interestingly enough, the rock n roll artist that caused me to pick up a guitar and take up years of streneous guitar lessons was none other than the "Nuge" Ted Nugent himself. When I first listened to the Double Live Gonzo album by Ted Nugent, recorded live in '77, I was hooked on rock and roll forever. In High School during the 80's I started a band, and we played Nugent tunes till our fingers bled. Some of my favorites by the Nuge are Great White Buffalo, Stranglehold, Hibernation, Storm Troopin and of course, Cat Scratch Fever. I use to play a awesome version of Hibernation that was over 13 minutes long. Unfortunately my guitars were sold 10 yrs ago or so, but I still have a fondness for Ted Nugent and his amazing fast finger style of play.
