This is from an article on the Guardian's website, entitled "'It's the screams of the damned!' The eerie AI world of deepfake music". (No link. They want your email, before you can read stories on their site.)
But the author identifies this as a "Deep Fake", "seemingly performed by Frank Sinatra". I'll just put that out there, for you cutup fans. Either any kind of mashup is acceptable as a "deep fake" these days, or the author decided to go for the sizzle without realizing he was looking at a salad.
