Go Away With … Kevin Olusola of Pentatonix

The son of a Nigerian psychiatrist and a Grenadian nurse, Kevin Olusola enrolled at Yale University intending on pursuing a medical career. But the classically-trained cellist and innovative beatboxer couldn’t resist entering the “Celebrate and Collaborate with Yo-Yo Ma” international competition, where he won second place. As a member of the a cappella group Pentatonix, the 24-year-old musician and his bandmates won the third season of the NBC reality series “The Sing-Off.”
