Perhaps you've already seen Kseniya Simonova's performance on Ukraine's Got Talent. But if you haven't, watch how she recounts the horrors of Ukraine's experiences during the Second World War. With sand.
It's one of the most remarkable, moving, beautiful pieces I've seen in ages. Since the video has already been seen 900,000 times I suppose she counts as a "Youtube sensation" but that term seems absurd and cheap when applied to this sort of thing. So too does any comparison with our own Susan Boyle.
Take eight minutes from your day and watch this. You won't regret it. The final words mean, I gather, something like "You are always with us".
You can see another of her pieces here.
