In the US the music of Dylan and G. Dead will likely outlive either British band. 60's Beatles music will survive a long time but that was a single decade. Stones, Dylan and G. Dead music are still performed live both by the survivors and many others (almost every large town and every city have Dead cover bands). Dylan's recent albums compare well with his early music, so he would take the creative longevity prize (and Nobel). Beatles stopped performing mid-60s but of course they are covered a lot today as well. Desert island for me: Beatles would be 3rd choice, stones not at all. Bob Marley would work just fine instead.
Beatles vs. Stones
Which do you prefer?
I'd have to go with the Rolling Stones although I do love Revolver.
And you?
