From shy to badass: 13-year-old singer compared to Janis Joplin

When 13-year-old Courtney Hadwin of Hartlepool, England took the America's Got Talent stage to audition she was visibly shy and nervous, but watch what happens when she started her performance. It's like the music possessed her (you know, in a good way)!

After her cover of "Hard to Handle," Howie Mandel, one of the show's judges, compared the young rocker to Janis Joplin. He then pressed the coveted "Golden Buzzer" which earns her a spot at the show's live performances.
