I know 2 things:  His name is Noah, and this is his Youtube channel.  I don't know much about him (yet), but a quick search reveals that one of his covers was given a boost when it appeared on Ellen's website.

He says that he writes his own music, but I LOVE what he does with his covers!  In this first video, he takes LMFAO's "Sexy and I Know It" and makes it tolerable!!

 

 

This one is U2's "Where The Streets Have No Name", and again, Noah makes it his own!

 

 

Now, I am off to search for more of his music... I need to find his original stuff (I might watch American Idol if they would let people like this perform!!).

Okay, here is the first EDIT: I did 9 more seconds of research and I found his Facebook page, he was on the Today show this morning, and he is only 18 years old. O. M. G.

Here's his clip from Today:
