I take anti-hero to mean someone who is out there busting their ass playing guitar, but not indulging in countless endorsements, selling songs to TV commercials, posing for magazines, etc. I don't think Nels is anywhere near against publicity, but I remember Johnny Marr basically calling out guys like Yngwie and others as non-genuine because of the way they sold theirselves. I'm not necessarily a big Marr fan, but I know his rhythm and songwriting skills are impeccable.
