Walk Off The Earth
A couple of years ago I found a group called Walk Off the Earth (official WOTE site). They'd done a cover of Gotye's Somebody that I Used to Know that went viral. Their official YouTube video of their cover has 170 million views -- so far.
I really love their funky style. Here's one of their recent videos, a cover of Adele's new song "Hello." (The link cuts off 1:14 of set-up before the music starts; the full video is at the end of this post).
Adele's song is awesome, and she's hard to beat, but I think that they've done it.
The guy beatboxing for them is Terry "KRNFX" Im (Korean FX, I guess). The guy on the left is one of the leaders of the group. He goes by the name Gianni Luminati. He plays bass, guitar, ukulele, banjo, mandolin, drums, vocals, theremin, glockenspiel, piano, cajon, cello, bongos, harmonica, double bass, percussion, kazoo, keyboard, kalimba.
Plus he beatboxes. And he's got an amazing voice.
The lady to the right is another mainstay, Sarah Blackwood. She's less versatile, and only plays guitar, ukulele, bass, glockenspiel, percussion, piano, mandolin, kazoo, and harmonica.
Also a great voice.
The guy on the right might be one of the other regulars, but he doesn't quite look like him, so maybe not.
Here's another video I especially like, a cover of "Roll Up". It shows Gianni's virtuosity, and also their creative style. He starts out by looping a bunch of backing beats and accompaniments, then does the song, sol, adding instruments as he goes along.
And below is an embed of the Adele video. You can skip the first minute or so, no loss.
