I'll be running a certain scenario with Mad things Drumming and am looking for appropriate music to fit the encounter at the end of the scenario. Something with heavy drums and percussion and not much else would be ideal. My thought is to have the song play the entire time the PCs are in a building and increase the volume as they make their way to the final encounter (sorry if I'm being too vague, but my players ghost these boards). So, hit me with your most thumping, barbaric, evil-sounding suggestions.
