I always love watching how songs come to life and change before the final product. I find it very interesting to see how they change and mold over time. Metallica was nice enough to let us inside the sessions where they crafted the new songs off Hardwired…to Self Destruct.  Another nice point is that we can also see the exact gear they used while tracking and creating the song. Something else we also get to see is how Lars’s hair really looks, which is… rather interesting.
