Just the other day I was amazed to listen to an AI-produced rendition of Yesterday by Freddie Mercury.
It does sound like his voice, but it doesn't do any of the things that no doubt Mercury would have done, none of his vocal show-off.
And this makes me think that classical music, where variations are more restricted and predictable in the case they occur, is a more fertile ground for this kind of experiment, which, with technology's upgrading, may result in difficult to spot forgeries.
