Stephen Coates

I need to double check on that one, but really, really, really cool.

And it became super popular and in the public mind a little bit more about 10 years ago when there was this guy called Stephen Coates, who is a musician and a researcher.

And he was in St. Petersburg and in a market and stumbled across upon some of these x-ray records and was like, what is this? And deep dived into it, has written a couple of books about it since then.

He had, I think it was a project called X-Ray Audio to just try and preserve like this piece of music history.
