He divided his recitation into an Acoustic and an Electric section; and in the Acoustic section he played us a fascinating example of a 20 year old Bob Dylan playing harmonica and singing with the recently 'discovered' Big Joe Williams in the blues, "Sitting On Top of The World" on March 1962.
Gray quipped that an older Big Joe Williams was working to sound vibrant, while Dylan was working at singing like he was 'old'.
Then he spoke about the 1964/65 period of Dylan's career as a 'cranking up of his reliance on the blues' as exemplified by the blues heavy recordings "Highway 61" and "Bringin' It All Back Home". These Dylan blues 'you've never heard before, but their words are part of the shared ocean of words that people use in the blues'. Once again, he said, Dylan managed to access the blues and be radical and conservative at the same time.
Gray went on to say, with a chuckle and a smile, that it was so typical so typical that Dylan would 'go electric' in 1965 right in the middle of the 'folk revival', which tended to believe that acoustic music was inherently the 'better' and more 'natural' and 'politically responsible' music of the two.
