Rob Trujillo always worked with the band during the recordings of Metallica’s new album “Hardwired To Self-Destruct”. We know that Kirk Hammett didn’t any contribution to new album. In addition, he was not in the studio environment either.

Everyone will accept the balancing role of Kirk Hammett in the band. In the absence of Kirk, the balancing role was undertaken by Rob Trujillo. 

Rob spoke in an interview with Metal XS and talked about how he balances the relationship between Lars and James. He said:

There is a lot of energy between Lars and James, and sometimes that energy can erupt. I know that before I was in the band, Kirk was the guy who was often in the middle, and it was important at that time. And now I feel like sometimes I’m the guy that’s in the middle between not just James and Lars, but even Kirk. I feel, in my life, in any situation I’ve been in, I’ve always been sort of in the middle.

With Suicidial Tendencies, there was a lot of intense personalities, and you had to figure out how to balance each guy and where they were at in their mood, or whatever was going on. With Ozzy, there was a lot of intense energy there too, ’cause he was battling a lot of demons. And sometimes you have a writing session, and he doesn’t show up, and, of course, you get angry, or you get frustrated, but you have to be cool — he’s the boss, you know what I mean? So there’s a lot of personalities in any of these situations that you have to balance.

In Metallica, I think it’s important that there… whether it’s myself of Greg Fidelman, our producer… He’s great for that, because he’s understanding of everybody’s personality. And then there’s the schedules, and all these things come into play, which can cause frustration in making a record, especially for the producer.

So Greg Fidelman is also a great happy medium in that balance. But it’s really important to have that with Lars and James. Like I said, I’m like Joe Walsh in the Eagles. Joe Walsh is somebody who… he’s a writer, obviously, and he’s a singer-songwriter, whatever, but at the end of the day, when it comes to the Eagles, he’s there to play guitar and he’s there to supply whatever is needed for that band, and that is what I feel with Metallica. Robert Trujillo in Metallica is to cater to the song and really look out for Lars and James, and Kirk.”
