Pentatonix hit the stage with Stevie Wonder at the Grammy Awards on Monday night, and the results were pure magic. The insanely talented group honored Earth, Wind & Fire by singing "That's the Way of the World" with Wonder. The chills-inducing performance, which garnered a standing ovation from the crowd, was a tribute to Maurice White, Earth, Wind & Fire's founding member who passed away earlier this month.
