Every band, especially those that have been around for decades and decades, has two or three albums that get lost in the shuffle, at least in my experience. It's not necessarily because they're bad albums, but maybe they're just not quite as good as the rest of their discography, and there's only so much time in a day, so I forget about them. For DT, I think that SC and BC&SL fall into that category.
With that being said, I listened to ITPOE yesterday, and remembered how awesome a song it is.
