When Kevin Olusola posted a video on YouTube celloboxing (beat-boxing while playing the cello), it got thousands of views and instantly went viral. Among the people who saw the video was a three-person a capella group in Arlington, Texas.
Once they saw Olusola’s incredible talent, they contacted him to see if he wanted to join their group for an audition to be on “The Sing Off.” A day before their audition, they met Olusola face-to-face.
“It was the day before the audition that we all — all five of the members — met for the very first time,” Olusola said.
The group called themselves Pentatonix.
