A cappella is a singing style that involves voices only – no accompaniment. While this in itself isn’t the most exciting thing, many a cappella groups try to press things by using their voices like the instruments they don’t have on the side.

In this awesome video, this choir brings back the theme songs of many classic Nintendo video games like Super Mario, Mortal Kombat, and Link.

Personally, I think the coolest part is the guy who gets to yell out, “Mortal Kombat!” (Was Mortal Kombat a Nintendo game? I thought the first one was a Sega Genesis game, but I’m not sure.)

I can’t believe this video hasn’t had more views.
