Lars Ulrich may feel his tenure in Metallica is fairly well established, but as a recent show in Detriot demonstrates all too well, everyone is replaceable.

In Lars’ case it was a young girl named Kendalynn, who was plucked out of the audience and sat behind Ulrich’s drumkit, where the drummer schooled her on how to rock Metallica-style.

She managed to make it through a few seconds of ‘Seek and Destroy’, which is way more than you have drummed in Metallica. “Oh, is that all?” asked Hetfield when Ulrich took over, no doubt scarring the poor girl for life.
