LP’s “How Low Can You Go” expresses themes of connection and vulnerability between two people in a poetic fashion, very similar to other songs included on the album Churches.

For instance, during an interview with Songfacts, LP delved further into this concept, thoroughly expressing some of the thematic ideas relayed in this song:

I’m always obsessed with this. It’s a bunch of stories about me moving from New York to Hollywood and always wondering if I’m getting out of control. I’m always like that. I always think about where your life can go if you let it… if you’re not careful. Or, if you are careful.
[…]
[It’s a representation of] an amalgam of many wild nights I’ve had in NYC and LA. Sometimes they stick with you. You have feelings for these characters and situations in all their flawed and beautiful madness.

Moreover, in terms of melody, LP wrote this song with their long-time collaborators, Mike Del Rio and Nate Campany; after combining a guitar track Del Rio had written years earlier, LP steered the melody into something that felt “sexy” with a “slinky beat”.
