Tragedy's A'Comin', the first single from the new Primus album Green Naugahyde (out 9/13/11) is live at Spin.com -- it's in a similar vein to Rumble of the Diesel from Of Whales and Woe with nice solos from Les and Ler.

And as long as you're in a head banging mood, check out We are the Lamb and Empires (part 2) from Kittie's new album I've Failed You (out 8/30/11).
