That brings up a good question-- uncool bands that are actually kind of good. I have to think about it, but this has got to be worthy of a thread. Remember, by listing a band that is uncool but kinda good, you're not saying that you like them, only that they're uncool and you kind of have to respect them musically, but you don't have to listen to them.
Prog rock bands should be disqualified from consideration, however, that their whole reason for existence is to demonstrate musical prowess and "elevate the genre." (And it's a genre I don't particularly care for)
