Let's start with a recording by The Piano Guys. If you haven't already heard of them and you're going to play piano, it's about time to know who they are! They are best known for creative arrangements of popular music, often mixed with classical tunes. They also manage to get pianos where you would normally not find them (like next to canyons, waterfalls, or even on the Great Wall of China) to do their videos. This one is from their latest album called wonders which combines Titanium by David Guetta with the classical song Pavane by Gabriel Fauré:
Extra Exploring: Listen to this other arrangement of Pavane for 12 cellos (since it was originally written for orchestra), then go back to hear how it was incorporated into the Piano Guys' arrangement.
You can also check out other Piano Guys videos on this playlist:
