Speaking of The Who,
I myself consider studio and live to be equally important, and the live shows and recordings elevate The Who near the top, as well as knock the Beatles down a few notches, they were broke too early and got off the road way too soon.
I know their songs and cover songs may not be up to snuff with my big 3, but the availability and quality of the Grateful Dead’s live shows is just staggering. If you are taking strictly live, they have to be at my top.
