Brass Against has done some great versions of Rage Against The Machine and Black Sabbath tracks in the past, as well as Tool. Now they're back with a double cover of "Parabol" and "Parabola" by Tool and it's awesome. The calm first half is really hypnotizing, while the second half comes right out and punches you in the face.
In other news, Tool just finished mastering their new record. Seriously.
