Walk Off the Earth’s A Cappella Cover of Taylor Swift’s “I Knew You Were Trouble”

Check out any end-of-year YouTube highlight video and you’re sure to see a glimpse of mega sensation Walk Off The Earth – who blew up online earlier this year with their 5 people/1 guitar cover of Gotye’s “Somebody That I Used To Know.” Boasting over 143 million views, that video has been held widely responsible for launching Gotye’s song into viral  fame.

Now, the multi-talented band joins KRNFX for an a cappella/beatbox remake of Taylor Swift’s hit song, “I Knew You Were Trouble.”
