Duds my ass. Street Hassle and Metal Machine Music rule, but I don't expect everybody to like the latter. And yes, The Bells is one that was under my radar for ages but it's at least as good as The Blue Mask which came shortly after.
Half of the rest of his discography too.  Debatable. The Blue Mask, Magic and Loss, New Sensations, Legendary Hearts, Conney Island Baby, & New York are all great albums. He has some duds to (i.e. The Raven, Street Hassle, Metal Machine Music). Berlin is and will always be my favorite from him.
