Elton John recently revealed in an episode of Elton John's Apple Music 1 that he's done "something" with Metallica. Of course my mind instantly jumps to Metallica doing "something" with Lou Reed, but then I remember it's Elton John and relax.
"I've just done something with Metallica," said John. "During this lockdown period, I've been working with Gorillaz and people like that. I haven't been doing any Elton stuff, but I've been doing great stuff with other people."
Metallica is moving at what drummer Lars Ulrich said is a "glacial pace" on the new album., but seem to have some other stuff going on. Like Hammett recording with Santana, or apparently an upcoming Metallica and Elton John collaboration. Seriously, I have not a single clue what this is going to sound like.
