I had a recording of the Revolutionary Etude, filmed on a phone (iirc), played on an out of tune Acrosonic piano (more a piece of furniture than a functioning piano), with no pedal usage, get copyright matched with a Sony published recording.

It's about as far from a professional recording as you can get on YouTube, except for some piano recital videos featuring ugly children inanimately reading their way through the sheet music.
