Jim Morrison, hands down. He said and did things that all of us think about, and wish they could do. He had the balls to do them, even though he was drunk 75% of the time and on the verge of being a high-level sociopath. Maybe *I'm* a little bit sociopathic, and feel like I can relate to some of his thoughts and actions? Who knows. Whatever the case is, the guy gets tons of respect from me. One of the best human beings to grace this earth, that I know about, at least.
He was my Mom's favorite in the 60s and early 70s too! She had the MISfortune of seeing The Doors perform in the early 70s, during Jim's darkest moments. So drunk that he really couldn't perform. Apparently back then, she said this was common. She also said Johnny Cash performed at her college and was in a similar state.
Most things are contextual. Take into context what OTHER bands were doing in 1966 and 1967, when The Doors first hit the scene and started playing some of their first (bigger, non-bar) shows. Read interviews with some venue owners or people who saw them for the first time, especially in 1967. They literally transformed "Rock-n-Roll", especially in the realm of performance.
