Hey, you can minimize artistic talent all you want. I think Eddie would have been successful at whatever instrument or music upon which he chose to focus. Party rock or the origins of hair metal not withstanding, I can't see how you're doing anything but trolling right now.
Imagine what he would have done had he not hampered himself with drugs and alcohol. Does methodology make one a great talent? It's just another means to an end of creating music. There are some scarily talented players around right now that went through rigorous programs of study to validate their musicianship and skill, but that does nothing dismiss Wes Montgomery's abilities that were based on his ears and hands. Similarly with many amazing bluegrass musicians and various worl dmusicians where the "method" is playing, playing a lot with other musicians. They aren't studying a method, but playing often. Some spend more time working on being a player and others on creating music...some of the best in any field combine a decent amount of both.
Anyway, I find the dismissive tone of some of these post as relates to music and certain genres disheartening. I'm all for to each their own, but...
All this said, I'm not a huge Van Halen fan, I just respect what he's accomplished and the influence he's had (despite not caring for the vast majority of the music he's influenced). Taylor is merely influential in her popularity as she's not doing anything even slightly new musically. It is vapid and trite...to my ears. I'll step away from this thread though, as it's going nowhere.
