Deadmau5 - Strobe (Evan Duffy Piano Cover)

This video is 100% worth watching all the way through.  I have always been intrigued by the striking similarities between classical and electronic music.  People are quick to discredit DJ's as musicians, as there music tends to come without words, and yet some of the most famous musicians of all time were composing instrumental symphonies in a similar fashion hundreds of years ago... Just with different instruments.  Strobe may have been the first Trance/House song I ever heard, and it remains one of my all time favorites.

Here's the original for good measure.
