Speaking in an interview made by Rock Baltimore, Metallica drummer Lars Ulrich explained that what will happens to Metallica without James Hetfield or himself. He said:
“I think a lot of it would [depend on] what the circumstances were. I always try to speak my momentary truth, and I’ve said a lot of shit over the years. [Laughs] And a lot of stuff comes back to haunt me, but at that moment, whatever I was feeling, it was my truth.
So if somebody leaves, it’s hard for me to imagine that we would not go, ‘You know, we’ve had a great ride for 35 years…’
But if somebody encourages the other three guys to continue, or there’s an injury… I’m just saying you never know what the circumstances are.
It’s hard for me to imagine that Metallica would continue [without its core members]. But you never know what the circumstances would be.
It’s a hard question to answer, and I just want you to know that I’m happy that I don’t get asked it very much. ‘Cause, as you can see, I’m just waffling along here, really. I don’t really have an answer. I’m just taking up time on the radio. I’m just tap dancing! [Laughs]”
