I like reading articles about Jimi Hendrix then going down to the comments and saying he was vastly over-rated to see all of the children gnash their teeth and weep. But it's true. Also, Jimmy Page was over-rated. Roy Clark blew both of them out of the water hungover. So did a dozen others.
Glen Campbell was by far the most underrated guitarist on the face of the Earth. You should go on YouTube and find that out for yourself. I couldn't believe it when I saw it. Most of these dweebs today have no idea how good Clark and Campbell were. Most of them don't even know how great Mark Knopfler was of Dire Straits. And Stevie Ray Vaughan might be the greatest guitarist I've ever heard in my life. Of course they've not heard of him either.
