As the driving force behind Ten Years After, Alvin Lee was a brilliant blues/rock guitar player... Admittedly, I'm only recently becoming familiar with his work, but I've been devouring it lately, and this song came up. The Bluest Blues has a great set of chord changes that gives some options both for playing the chords, and soloing over them. So I hope you'll take some time and play around with this tune and add it to your repertoire, it's a good one. Website - https://BluesGuitarUnleashed.com
