Zepplin, Van Halen(all albums, including III), Steppenwolf, Rare Earth, Iron Butterfly, SRV, Hendrix!, The Who, The Guess Who, Edgar Winter Group(Frankenstein), Clapton, Cream, The Doors, I could go on and on and on.
If I were asked to pick one favorite, I would not be able to.
Sometimes, I mean Sometimes... I can even stomach 70s "Corporate Rock" aka Boston, Styx, Kansas, etc
