I'm having a hard time coming up with something concrete myself. The 'cheating' answer would of course be North Korea.

For something more practical, targeting an older segment of the population, or a remote area in a non-English speaking country might do it.

Lady GaGa playing a piano in the same location is probably your best bet.

Practically no one recognises her without here insane make-up and get-ups (Which I think is a pretty smart ploy) and a piano is a piano yet she is in the same "Generally recognised superstar" category as beyonce and she is a very good pianist.
