Cover art for Alpha Incipiens lyrics by Mountain Goats, The

I always saw this song as an extended metaphor comparing the beginning of the alpha couple relationship to an impending hurricane or other natural disaster.
I like the interpretation that it could be compared to a nuclear explosion, too. There is definitely at least one other song likening the alpha couple relationship to a war ("International Small Arms Traffic Blues" on Tallahassee).

Yeah, I always felt that too. Especially with the last lines- "the only thing i know is that i love you, and i'm holding on."
