Once you can do something perfectly, the only thing left is to learn to do it faster. Take Peter Grigorov for example. He's playing "Flight of the Bumblebee" on the accordion at 20.3 notes per second, setting a world record in the process.

Color us impressed. This doesn't seem like it should even be physically possible, does it? It's almost enough to make playing the accordion seem cool.

Watch the video below and see if your eyes can manage to follow Grigorov's fingers.
