This is the instrumental track for the mash-up with the same name.  Sometimes the vocal might bury some of the more interesting things about a mash-up such as this.

These mash-ups are not as simple as taking Instrumental A and fitting Vocal B to it.  It's actually a lot of beatmatching separate stems and finding where their individual phrases line up.  Then to make sure they're in the same key (which actually is some hardcore nerdy music theory shit.  For example, A Place For My Head is in Eb Phrygian mode, while No More Sorrow is in Eb Harmonic Minor.  

Yeah.

Also, the song switches from 4/4 to 12/8 at the climax, but the quarter note pulse stays the same.  I kept this mix at 133, which seemed like a good average of BPMs involved.  128, 135, 133, 135, 140.  I erred slower because that 128 is the main vocal from Darker Than Blood.  With vocals, you want to try and move it in time / key as little as possible from its original key.
