Okay, poking the back catalogue... An album like every two weeks. That's pretty much not humanly possible without using procedural generation. So I'm beginning to suspect this is the case. But it is also really good, so I'm confounded.
I actually posted this because it's new Aleksi and I'm a fan of his Astrobotnia work and Project V. I didn't notice how often he was releasing new albums until after I made the post and then figured maybe I shouldn't have posted it lol. But I'm glad you like it!
It might be partially automated generation like you said, maybe some fractal type thing, like some custom software with L-System strings https://en.m.wikipedia.org/wiki/L-system
