YouTube sensation Smooth McGroove makes theme songs for popular video games by recording sections of each song individually and then playing them back together. What's special is that he does all this with nothing but his voice.
In his latest video, he recreates one of the most recognizable video game songs of all time: the Overworld theme from Super Mario Bros. 2. In the video, this big-beard long haired man plays eight videos of himself making particular noises that all match up to produce the iconic theme song. In the middle of the video are graphic from the game itself. Smooth McGroove's other acapella sound tracks include Sonic, Donkey Kong and Street Fighter, to name a few.
