I enjoyed the piano stylings of Lord Vinheteiro in this "Evolution of Music" video**. He plays a little music from each year, starting with 1680 and ending with 2017. There's Beethoven, Iron Maiden, Aqua, and more.
Another fun video of his has him playing the soundtrack and sound effects from Super MarioWorld on the piano along with the video game itself.
**Though I found his staring at the camera a bit jarring!
