I was with a friend cd shopping when we ran across this one, after looking it over he decided to by it. After listening to it we were both impressed with it, so I got on Amazon and bought me a copy. With further listening I found this to be pretty good, the sound quality on most of the tunes is pretty good for the time period. From what I have learned this is early to middle sixties, it is from the time they spent with the Yardbirds. There is a lot of great guitar playing from these three, the tunes sound like they are very raw and early. This is all Blues for sure, so if you like good raw early blues, this would be a good choice. There is not a lot of vocals just jamming for the most part, to me it is still worth having.
