In an interview with Newsweek, Adrianne Lenker explained the inspiration behind the title “Capacity”:

There’s a story there, too. It involves a close friend of Lenker’s who writes short stories and novels. “She always has a hundred stories in her brain, and they all have different worlds that she’s created with different languages she’s made up. I remember asking her, How do you possibly remember all this stuff? How do you have the capacity to hold all this in your brain? She told me she doesn’t think about humans having a certain amount of capacity. She feels like it’s unlimited. Just thinking of myself as a vessel. I’m starting to think of myself as something a little bit more translucent. Something that doesn’t necessarily contain and hold things, but [they’re] actually flooding through me.”
