Speaking of "The Hollow", Keeley says: "The title-track was made in reaction to reading an article about a woman suffering from postpartum psychosis, and a really tragic end. I felt so connected and moved by this. I wanted to force myself into the same space that she might have felt, or I imagined that she felt, so I could at least feel that she wasn't alone. So in the song there is reference to "there is no help here, not for me" and also the highs and the lows of the strings referencing the resonance in one's mind as you're losing control to this horrendous mental illness disease."

The track follows previous singles "Horse" and "Turning" featuring Colin Stetson.
