Pumping: Mos Def — Black On Both Sides

This is still undisputably Mos' best album (unless you count his Black Star collab with Talib Kweli). It's a real shame he fell off for a while there, because there's some great beats and rhymes on this one, and it focuses on holding those who are effing up the world accountable. It's also sort of a shame it preceded the Bush administration, if you think about it.
