Ever heard of 'The Piano Guys'? They're a group of musically-minded maestros who regularly reinterpret songs in a unique and extraordinary way. Just take a look at their latest piece, 'Rockelbel's Canon', which we've embedded for you above.
That's right, 'Rockelbel's Canon'. Not Pachelbel's Canon, the eight note classical staple of weddings all over the world, but 'Rockelbel's Canon' - the same piece but with a really rather wonderful twist.
To tell you exactly what they do with it would be spoiling it slightly, but know this: it's glorious, and pretty addictive. In fact, if you want to be able to listen to it whenever, wherever, then download the MP3 here and whack it on your iPod.
