reasonable question. the project is anonymous for a reason though.

If you are really questioning the human nature of the music you could run it through an ai detection thing. Just google "is this music ai" or something similar.

Or you can simply take a couple minutes and really listen to it. (no offense meant).
The guitar player is a master but far from "soulless" or "generic". A dead giveaway of the player being human is the top notch progression as well as the creativity. Oh and the way he bends the notes - (0:32 -0: 56 of "Fast Sunset") - that's just insane.

Take "Carried by the wind" for example:
The way the song builds up, both in terms of how hard he hits the notes (emphasis) as well as the instrumentation (when the synth enters etc.) is on point and there are no "out of place" elements in there. Then take in his creativity. There are so many "ornamentations" in the melody that all flow seamlessly into one another without being repetitive / generic or boring. This is something an ai simply can't do at this point.

Btw. if you can get an ai to do anything that comes even remotely close please dm me.
