This is probably done over and over again but what the heck. It is my personal belief, or i would like to think that rock music was primarly influenced by blues music. I know it's impossible to pinpoint one genre as the sole influence of a totally other genre but in this case it proves to be true EX. Led Zeppelin, Chuck Berry, Jimi Hendrix, Stevie Ray Vaughn. I guess what i am wondering is who do you think was probably the most influencely blues artist to rock n' roll? I personally think it was robert johnson.
