So, what should he play?
A Canadian cellist has recorded a cover version of Katy Perry's single 'Roar' right next to a live tiger.
The video, made by CBC, shows cellist Kevin Fox playing a loop-pedal version of the song while an adult tiger lays beside him.
Fox comments on his unusual duet partner in the video: "I don't think there's anything that can prepare you for the sight of a real full-size tiger."
