I think Son House is more of an influence on me than RJ. And he was also BEFORE Robert. Son had to shoo that pesky kid away, 'cause he couldn't play and he always INSISTED on sittin' in.
Then of course, he DID go away... and came back a Blues Virtuoso! HE was the first guitarist to epitomise the "guitar hero", while Son and Willie Brown were singer/guitarists writing or interpreting Blues...
Robert also stole a bit from them too...
