Well, let's face it. When a guitar player gets some run, we all turn into a bunch of petty catfighting women. The instrument is just so versatile that we could debate whether you're supposed to create sloppy attitude filled songs on it or study the technical aspects of it and rip forever.
Everyone is looking to validate the way THEY play and everyone can point to someone who has succeeded in playing the way THEY play.
So, as a technically proficient guitar player, and without trying to invalidate anyone else, I'm going to let Al DiMeola make my case:
"You need both abilities: To be able to sing a melody and play with space and also to have the requisite technique to play the most intricate music. That makes you more complete and able to play a wider variety of music. It's a bunch of bullshit every time guitarists say, "One note says so much more than 100". I always laugh at idiots who make that claim. Tell that to a flamenco player or a classical player and see what they say. It's almost a defensive reaction. They take something they lack, attack it, and claim they never wanted it in the first place. Sure."
I don't think it can be better said than that. I think why we (unbelievably, if you ask me, attack Stevie Ray Vaughn, Jimi Hendrix, Jimmy Page, and Eric Claption) is that they actually learned their craft and play it well. We don't debate the merits of the guitar players in Korn, Limp Bizkit, or Creed because, quite frankly, if you know anything about the guitar, those bands musical ability is borderline offensive.
Take a step back. Those people I just mentioned in parentheses are the best there are. We ought to be working diligently to restore real rock guitar to the airwaves rather than attacking the real McCoy.
Again, though, just my opinion. ;-]
