where i found it: everywhere
Any semi-close listening to early Elvis Presley will probably bear the verdict that we all owe a big debt to Scotty Moore for incinerating the modern rock guitar into existence. If, for whatever poor reason, you've never paid much attention to this dude, now is your chance. Sure he has his own debts to pay to Merle Travis, Chet Atkins and a whole heap of black folk, but he's got his own way and his own energy, fully in action in the examples below. It's sounds kind of fluid and easy, but I dare you to try to reproduce same. I'm not making any comment on Elvis' ridiculous and unbelievably great vocals, maybe on a different day.
