Yes, I agree with you. The Yardbirds and their time with Jimmy was indeed very innovative. I like to look at the evolution of that band, the way that when they had Clapton they were very blues, then Beck they went more pop, and finally with Jimmy where they became experimental and psychedelic. When he joined the band the band really changed, and in my opinion, they changed to the purest form of their musical talent. A great band.
