Speaking of voices I've been watching AI covers, Kurt singing what he never sang. This is still the best cover I've heard recently though because it's a group of siblings.
I'd post the Kurt Cobain AI covers, they do copy his voice but not his inflection and they are too perfect in pitch when Kurt would go off key at times so it's not authentic and not impressive enough yet. It's interesting to hear however, singing songs and covers artificially.
