I Knew You Were Trouble - WALK OFF THE EARTH Feat. KRNFX

If you haven't heard of these guys the you're definitely missing out. Walk Off The Earth became a youtube sensation with their cover of Somebody I Used To Know all on one guitar. I'm usually not one to post covers,  but this one impressed me quite a bit. Covering a fantastic song, depending on who you ask, they combine an all-natural a capella background with some clean vocals from the lead singer. Wait a minute or so for some cool dubstep beat-boxing. Enjoy!
