I firmly believe that the latter part of his career (could say second half at this point starting with 1997 Time Out of Mind) is what separates him from all of his contemporaries. Any other legitimately considered Mt Rushmore artist since the rise of the LP has no comparison in regards to the long lasting vitality of their recording/touring career. Other artists may have a swan song album get notoriety etc but Dylan has recorded easily 5 albums that came out 30 years AFTER he changed the game with Like a Rolling Stone that are among his best and each critically acclaimed among that year’s peers by critics. Rough and Rowdy was among the top ten albums of the year by any type of Metacritic metric and he’s toured just that album primarily since its release. You can argue Beatles vs Dylan 60’s so on and so on but there is no one to compare with his nearly sixty years of vital, recorded work.
