LARS ULRICH Is 'Thinking About' His 'Brother' JAMES HETFIELD

Lars Ulrich says that he is "thinking about" his "brother" James Hetfield, just days after the METALLICA frontman revealed he was returning to a rehab program.

Last Friday, METALLICA's tour of Australia and New Zealand was called off so that Hetfield could enter rehab to battle his addictions. The trek was slated to kick off on October 17 in Perth and was to include over 10 dates, with SLIPKNOT in the support slot.

Over the weekend, Ulrich took to his Instagram to share a photo of him with Hetfield, along with the following caption: "Thinking about my brother. ....sending love."

The 56-year-old Hetfield has been open about his addiction and alcoholism. His struggles were detailed in the 2004 documentary "Some Kind Of Monster".

A couple of years ago, Hetfield said "fear was a big motivator" in inspiring him to get clean. At that time, he said he was sober for 15 years.

In a 2016 interview with Australia's Rolling Stone magazine, Hetfield talked about the interpersonal relationships between the METALLICA bandmembers which reached an all-time low in 2001 during the making of the "St. Anger" album. He described the dynamic between him and Ulrich as: "Lars is, 'I have to do everything, or else it's wrong.' He's got the weight of so much on him. And [METALLICA's song] 'Atlas, Rise!' started out as a, 'Here, let me help you with that. You don't need to carry all that, brother.' And then it morphed into more — and this is not specifically him, but I'm plugging him into this — I think he likes that. There's a drama that makes him work, and we all have a bit of that. He wants the control but he doesn't really have control. The illusion of control, and then the ability to complain about how you have to do everything yourself, and then you still do it."

Hetfield continued: "There's some 'Psych 101'. But relationships, my God, every day I learn something, and relationships are teaching me about what's important. I went through a lot of stuff in 2001 [as captured in the 'Some Kind Of Monster' documentary], that was kind of my freak-out period, realizing my life is not working how it is now. And it took a huge bottom to realize that. And I think everyone in the band has hit their bottom in a certain way, a different way, over the past 10 years. There's been some realizations. It's just the age — between 45 and 55. Fifties. That's a number where you think, what the fuck am I doing? [Life's] more than half over! But the relationship with Lars, we've been friends for a long time, it's lasted longer than all the marriages in the band. God, we hate each other, and we love each other, and it morphs, it changes, but at the end of the day we realize, this works. And we're a good team, man. Trusting him: 'Yeah, I've got 800 riffs, and here they are. You edit them, you pick out the good stuff.'"
