Last year, Russian percussion band Etnobit recorded themselves creating incredible music by drumming on ice shards on Siberia's ancient Baikal Lake. You won't believe it.

According to the Siberian Times:

How did they realise they could make their own Coldplay on Baikal?

[Said Natalya Vlasevskaya,] 'The wife of one of our drummers, Sergei Purtyan, slipped and fell down, and as she landed on the ice, she made a very musical 'boooooom' sound - so nice and deep that her husband, who has a very good ear, said 'Hold on, what was it? How did you make that noise?' . . . 'So we walked to the same spot where Tatiana, our drummer's wife, fell down so fortuitously, and started touching the ice, feeling how it sounded' . . .

In fact, for some reason, the ice in other parts of the lake does not produce the same stunning results. While Baikal is 1,642 metres (5,387 feet) deep, in this part of the lake there is only five metres or so of water under them as they perform . . .

'People later asked us how we found the spot where different bits of ice sounded so much in harmony with each other.

'The answer is, I don't know. This is just how was. This is perhaps what I mean by saying about it being the wonder of Nature, that all we had to do was to discover that place, get there, and start playing.'

Since the video came out, there has been a lot of skepticism about whether the ice drumming is real. Is this just a clever edit, or did Etnobit really record those sounds on the ice? Why can't we see any microphones in the shots where they're drumming? Why is this one spot particularly prone to sound, but others aren't?

No matter how skeptical you are about whether the drumming itself is real, this is still a fantastic video that will make you feel a little sunnier on even the coldest winter day.
