Cellist Kevin Fox Performs Classical Version of Katy Perry’s Roar Next To A Live Tiger

Canadian cellist Kevin Fox performs pop star Katy Perry’s ‘Roar’ using a looping pedal board featuring guest artist Tobby the Tiger. “I don’t think there’s anything really that can prepare you for the size of a real full-sized tiger,” Fox told CBC Music. “I was surprised I wasn’t freaking out more. It’s something to tell the grandchildren.”
