You probably know Brass Against from their jazz-metal covers songs like "Ænema" by Tool, "Know Your Enemy" by Rage Against the Machine, and "My Own Summer (Shove It)" Deftones. Now you get to know Brass Against for their own material, as they've just rolled out "Umbra" from their debut EP due out April 10.
If you thought their covers grooved hard as hell, wait until you hear this one!
