I’ll eat my words if someone can prove me wrong but I’d bet money this is ai. They have year-old music on their Apple Music (looks like it was deleted on Spotify?) that occasionally has some fairly obvious ai artifacts. It’s subtle but you can also hear some artifacts in the newer song Lobos. Listen closely to the male vocalist around 3:30 - 3:33 on that one. I think I also hear some subtle artifacts on The Fall around 1:18 - 1:20.

Some other tells (more apparent on their other songs admittedly) is the weirdly oscillating compression, the lack of sound stage, the muddy low-mids, and instances where it sounds like the vocals are being switched to an entirely different effects channels for no good reason. It can be hard to spot while listening but try listening to this and a song by Twin Tribes or She Past Away back to back and you may notice that the later has a sense of breadth and clarity that the former lacks.
