Freddy King is perhaps the least known of the blues Kings (BB and Albert the others), but Freddy had a great instro style. His Hideaway has always been a favorite tune of mine (and frequently covered by others such as Clapton). Hideaway is a classic and unique blues style.
Now I'm not a biggie on the You Tube thing, but I have to admit, there is some incredible stuff there. I found this Freddy King video and thought I'd bring some attention to it. He plays a basic Hooker riff, almost to boredom, then suddenly digs for it, and things get really intense. A hot performance.
