Metallica began previewing a new single on TikTok, with each individual band member joining in as a duet day after day. Now all four members have joined in and Metallica has revealed they’ll release the song titled “If Darkness Had A Son” tomorrow, March 1. A few notes on the duets:

• James Hetfield looks great! Dude looks like he’s having a blast
• We need Robert Trujillo to break out that Flying V bass way more… and we need his dog to try and steal his cables way more
• Kirk Hammett has a nice house
• Lars Ulrich, drummer

Watch it below and stay tuned for the single!
