From the album Carpet Bed EP
This is a song about someone severing from their father not because they finally stopped loving him, but because they realized rescue was never going to work. The speaker addresses him directly while announcing his damnation, which means they're still trying to communicate with someone they've already declared unreachable. The repetition at the end isn't closure. It's the speaker forcing words into his mouth he'll never actually say.
Daddy, there's pain in your smile / I've never seen you so dark
She's reading suffering in his face but calling it darkness, like she can't tell the difference between him being in pain and him being dangerous. That confusion is the whole problem: she keeps trying to diagnose what's wrong with him instead of just leaving.
Mama took the key and she ran / The baby's blood is on your hands
The baby is never identified. Could be the speaker, could be a sibling, could be something worse. Either way, Mama got out and took the exit route with her, which means the speaker is stuck addressing someone who destroyed the family but won't name what he did.
I tried to pull you out / But you built this bed to rot
Past tense rescue attempt right before announcing his damnation. She's explaining why she's done now, but the fact that she tried at all means she still believed he was salvageable until very recently. The song is her realizing he chose this.
It's all your fault
The repetition should feel like release, but it doesn't. It's either the speaker joining him in self-blame, forcing him to say it out loud, or saying it for him because he never will. I'm not sure which is worse.
The title 'Antlers' doesn't appear in the lyrics, which makes them a ghost image over the whole song. Antlers are something you grow after surviving violence, or something sharp you carry that marks you as dangerous. Either way, the speaker is naming what her father became without being able to describe what made him that way.
