Charles McGrath in the NYT:
In many ways “Dancing” is an almost perfect piece of Internet art: it’s short, pleasingly weird and so minimal in its content that it’s open to a multitude of interpretations. It could be a little commercial for one-world feel-goodism. It could be an allegory of American foreign policy: a bumptious foreigner turning up all over the world and answering just to his own inner music. Or it could be about nothing at all — just a guy dancing.
However you interpret it, you can’t watch “Dancing” for very long without feeling a little happier. The music (by Gary Schyman, a friend of Mr. Harding’s, and set to a poem by Rabindranath Tagore, sung in Bengali by Palbasha Siddique, a 17-year-old native of Bangladesh now living in Minneapolis) is both catchy and haunting. The backgrounds are often quite beautiful. And there is something sweetly touching and uplifting about the spectacle of all these different nationalities, people of almost every age and color, dancing along with an uninhibited doofus.
Children, not surprisingly, turn out to be the best at picking up on Mr. Harding’s infectious vibe. There’s frequently a grown-up, on the other hand — especially one in the front row of a crowd — who tends to ham it up and make a fool of himself.
The other remarkable thing about the “Dancing” phenomenon is that it is, to a very considerable extent, a creation of the Internet. It doesn’t just live, so to speak, on the Web; it was the Web that, more or less accidentally, brought it into being.
