as much as I have appreciated Lone Pilgrim's post, I must say it is a real stretch to say Dylan's music is underground.
dylan's music can without any shadow of a doubt be considered *mainstream*, if not *THE* mainstream.

, together with the Beatles, Presley and few others.
Few people in the world don't know Blowin/Knockin/Lars.
not to mention the fact that he's the *creator*, so as to say, of electric folk and folk rock, in a way.
yes, there are angles of his work which are difficult and *high register*, but what difference does it make?
To say Dylan is underground is like saying Mozart, Bach & Beethoven are.
Paradoxical.
