This song is about the forging of two people's minds, and the difference in interpretation that can arise from ineffective communication. It's about not listening properly, and about reacting before thinking. Metallurgy was written in late October of 2015, after a trip to visit an old girlfriend that ended very poorly.
lyrics
The ties that bind are wrapped tight like a tourniquet. From the time you told me, I was confused and sad to go. But, I don't know why she abused me, I just had to be assured. And I don't know what paths we're choosing, but I just hate to lose control. And I don't know why I try to hold it together, but baby I'm sure you do. You just had to know.
