Metallica had a rough period about 15 years ago, as detailed in their "Some Kind of Monster" documentary, which, by the way, is one of my favorite music docs.
Now, Lars Ulrich is detailing that time and revealing what band kind of brought Metallica back together!
"The Rolling Stones called us up and said, 'Come and play some shows with us in California,' and we sort of agreed," Ulrich tells The Sun. "You're not going to say no to the Stones, so that was it."
Thank you, Mick Jagger! XO -Anne Erickson
