Which is very interesting. If I'm not mistaken it's also the first time that an acoustic bass is used while the guitars switch to distortion. In BOTWH and TRATB the bass is used for the intro (and outro of the latter), in The Clansman it's used while clean guitars are playing. DOTC uses it during clean and distorted parts. Has a very interesting sound and I like the experimentation.
