Smooth McGroove has gone from being just another dude who looks like Jesus to one of the world’s most popular Youtube Acapella artists. What makes it even cooler is that he’s not doing it with top 40 hits or any of that garbage, he’s creating and performing insane arrangements of classic video game themes. We’ve posted a few of his videos in the past, but his newest one, the Theme from Tetris, is one of the most impressive to date.
