This youtube link goes to a full Led Zeppelin II album, styled as if it was recorded in the 50s. I can’t tell if this is Ai, but it’s astoundingly good musicianship. I have listened to it multiple times.

Pretty sure, almost 100%, this is all AI.
If you click on his YouTube profile, you'll see he has several famous albums from Kiss, Judas Priest, AC/DC, Van Halen, and more all recorded to sound like 50s albums.
And if you click on his Patreon link, he's selling all of them for $9.99 (even though they're on YouTube for free).
I can't find much info about him but this stuff is as easy as generating an AI request "Make Led Zeppelin II sound like a 50s rockabilly album." Adjust a few parameters, click a mouse, and wait.
