With dual references to the movies Eternal Sunshine of the Spotless Mind (2004) and Harry Potter and the Half Blood Prince (2009), “Lacuna” is an exploration a person’s ambivalent relationship with their own difficult and treasured memories.
Baxter supplies the following as a synopsis of the song:
...
(Andy Baxter and Kyle Jahnke)
Memory, show me
Change for a date night? Tragic
Cash from a coin star? Magic
Learn what a tongue is for, smart aleck
Please
Oh, take it, vial and hide it
Cure me, I wouldn't fight it
I can't see that evening
I'll quit trying to
Siphon even
All the very good ones please
(Both)
Honestly I can't remember what I can't remember
But I'm at ease
Cloudier now with serenity
Shaped like a doubt wrapped in gauze could be
(Baxtеr)
I can't figure out at all what I need
Ooh-ooh (Ooh-ooh)
We're on thе couch, we're neckin'
Habits abound, still checkin'
I'll salvage pocket change, I reckon (You)
Lacuna was written by Robert Andrew Baxter & Kyle Jahnke.
