Adrian Romoff is only 9-years-old but he’s accomplished more in his nine years than most of us will in a lifetime. Oh, and his musical abilities? They’re off the charts. That’s why the judges didn’t think it was really him playing when he auditioned for America’s Got Talent.

Adrian has already skipped five grades, has had concerts at Carnegie Hall, took third place in the American Protege International Music Talent competition, and appeared on The Ellen Show. Did we mention he’s only 9-years-old?

When Adrian auditioned for the ninth season of America’s Got Talent, the judges had no idea what they were in for. The talented kid opted to play the very complicated “Flight of the Bumblebee” on the piano.

“Are you exhausted now?” a visibly shocked Heidi Klum asked. “I’m exhausted from this.”

“Well you’d be even more exhausted if you were doing this,” replied the out-of-breath contestant.
