11 Minutes of Pure Beatboxing Genius

Using only his voice and a microphone, Australian beatboxer Tom Thum gave a dynamic performance at TEDxSydney in May. His 11-minute act was uploaded to YouTube earlier this week and instantly went viral, accruing more than 1.4 million views in two days

After a fairly straightforward start, Thum puts a unique spin on Michael Jackson's "Billie Jean," followed by a succession of beats inspired by Aboriginal Australia, India, China, Germany and American jazz.

Thum is a natural on stage: He cracks jokes and impersonates others' voices. In 2005, he won the Beatbox Battle Team World Championship alongside fellow entertainer Joe Turner.
