Walk off the Earth are stupidly good

So unless you've been living in China or somewhere you will have heard Somebody That I Used to Know by Walk off the Earth, which has exploded via novelty viral video and super-talented  vocals and teamwork. I may be unfashionably late to this party but my girlfriend has been delving into their other stuff and it all seems pretty bitchin'.

So here's a cover of Magic by B.O.B., which is a choon by itself btw.

Some points though...

• I preferred the long haired guy when he was playing the socially awkward, fggty upset guy in the other video.
• Srsly what is he wearing on his head, is he actually a wigger? 
• Clearly there's studio 'trickery' going on. Or does everyone know that? I'd love to think they pulled this off in one take but unless they're looping their own vox as they go along...hmmm..
• I actually love the choreographed instrument change/throws...
• Super jelly of their setup tbh.

And look, look, they know their memes! Nerds will inherit the earth....

 So yeah, they're all over the jewtube.
