A Myaskovsky Clarinet Concerto?

[Theodore S.]

This is indeed a strange mystery! I'm having a look around on the internet, and now I have to wonder if anything but the fact it's a 3-movement concerto for clarinet and strings is correct, like the credited musicians. At the very least, it's very probably not by Nikolai Myaskovsky.

I did see that the conductor Vladimir Ponkin is online and has social media (his own website and a VK account) - perhaps he'd be able to help solve this mystery, considering part of it is under his own name, after all.

It might not be a concerto for clarinet and strings originally, either (This does not aid identification!)
