Sean - no, probably hard to defend much after 1980 (Hotter Than July), apart from 2005's A Time To Love which was pretty well received. But hey, who knows - maybe his arc is just beginning its belated upward curve? Even if it isn't, a high percentage of his output from the mid '60s up until 1980 should make him a serious contender for '(previously) most musically creative person (still working) in the industry'.
