It goes without saying that Bob Dylan's influence on modern music is enormous. Dylan didn't invent folk ("Mr. Tambourine Man"), or protest songs ("A Hard Rain's A-Gonna Fall"), or maybe bizarrely, even hip-hop ("Subterranean Homesick Blues"), but he certainly laid down a blueprint for others to follow. Volumes exist that chronicle the contributions of this legendary figure. Suffice to say, it's a big deal when Bob Dylan and his band hit your town for a summer tour. Mavis Staples opens the show.
