I think if she had been one of those YOUTUBE KIDS that kills it on super advanced metal songs (you've seen those videos right?) that LARS woulda let her stay up there!!!
This was in Detroit, but it wasn't big names of the band making headlines, it was a guest appearance during their show at Comerica Park last week, when Metallica welcomed a small girl named Kendalynn onstage.
As a young metal fan, they let her perch behind Lars Ulrich's drum kit and play around a bit for the crowd. While they didn't let her stay for long, she did look adorable in her oversized, noise-cancelling headphones.
