Don't lump em together
but for what its worth, its a very easy thing to do. I've always seen Unwound's sound as more in your face and aggressive where as Polvo, while similar, takes a step back on some songs and has some fun with themselves.
And this week has surely been shitty. And now it's not raining or snowing outside, it's icing. Dammit.
edit: Has anyone seen this show, "Are You Smarter Than A 5th Grader?" Well, I never thought people could ever be this stupid but apparently i'm wrong. America is fucking sick.
