Season six runner-up Blake Lewis returns to American Idol to perform on Fox Reality Channel's American Idol Extra on Thursday, May 14. He will be doing a cover of Disturbia by Rihanna, or course in classic Blake Lewis beatboxing style.

Beatboxing is a form of vocal percussion which primarily involves the art of producing drum beats, rhythm, and musical sounds using one's mouth, lips, tongue, voice, and more. In Blake's case it involves singing as well to create an eclectic blend of hip-hop and pop sounds.

He also has a great new song out How Many Words and you can find much more on his official site.
