It's another one of her club tracks. Just not really why I listen to her. Though I will say it's better than other things she's released (or shared on social media) with this sound.
I was on the Grimes Reddit and saw a post that a Grimes song called “Darq Souls” shows up on streaming under the artist name Carla Sanchez so I went to check it out and holy crap this is good, like 4aem good. Sounds like a demo/unfinished though and most likely not supposed to be there. edit: gone but still on youtube. Song is so good though.
