One thread prevalent throughout this blog is artist's observations about how they're often not really sure where the creative impulse comes from or how, exactly, it's harnessed. Singer and performer Mitski sums it up nicely:
Every song i write feels like the last song I'll ever write, and the moment it's done I fully forget how I did any of it lol. if artists were fully honest in interviews half our answers to Qs about "process" would probably be "i don't know dude."
