A lot of professional and amateur music critics compare Interpol to Joy Division. Everytime I see this in an article or some blog, I usually instantly discredit the person making the statement as ill-informed. They are usually just repeating this from some other ill-informed article.
I think most people who really listened to post-punk from the 80s compare Interpol to The Chameleons UK, musically, and Kitchens of Distinction, vocally.
