I don't know that I would take a hard line on it, but I think what most folks consider their "classic period" is I&W - SFAM. Even though there is a lot of diversity in that period, I think you can definitely say, looking back, that there is somewhat of a defining sound to that era of the band, and that is what produced much of what people would consider to be the true DT "classics."
So, back to the discussion at hand, I don't find that the new album sounds a lot like that era, IMO.
