I enjoyed the movie, but the best part may have been discovering Link Ray. During the movie, Page played a record by Link Ray, "Rumble", as an example of one of his early influences and the attitude he wanted to capture in his own playing. Though I recongnized "Rumble", I was not familiar with Link Ray. My wife immediately went out and ordered "The Best of Link Ray" from Amazon. It arrived over the weekend, and I was blown away. This guy was playing ferocious distorted guitar back in the fifties. People say he invented the power cord. I don't know if that true or not, but after listening to the CD, I have no doubt that this guy showed others how to play distorted rock guitar. Evidently, he was a big influence on Paige, Townsend, Clapton and many others. If you get a chance, you should check him out.
