Out of the four members of Metallica, Robert Trujillo might be the one with the best on-stage presence. There's just something about the bassist that separates him from his bandmates. Not that Ulrich, Hetfield and Hammett all don't contribute to the energy and intensity during live shows, but it's hard to argue that Trujillo simply owns the stage.

From his signature helicopter spin to his barking vocals, Trujillo is a musician few can imitate. We could post thousands and thousands of photos of Trujillo doing what he does best, but we decided to try and whittle them down to just a handful. Sometimes in rock bands, you'll find the bassist is more subdued or prefers to stay away from the spotlight; with Trujillo, he commands the attention of the crowd, and Metallica's live shows are that much better because of it.
