Courtney Hadwin stunned the judges of America's Got Talent with her voice, a 1960's soul vocal powerhouse in the body of a 13-year-old British schoolgirl. Her audition of Otis Redding's "Hard to Handle" landed her the golden buzzer, allowing her to progress straight to the live rounds. 

Hadwin, although young, is quite the seasoned singer. She was a finalist on The Voice Kids U.K., and has a whole YouTube channel dedicated to covers of big hits from the past. "You are not from this era," Howie Mandel fittingly noted during her audition.

We've rounded up the singer's six best performances prior to her AGT appearance. See below, and try to keep your jaw off the ground.

At Last - Etta James

I Got You (I Feel Good) - James Brown
