Metallica are “beyond psyched” to have ‘Master of Puppets’ feature in ‘Stranger Things’.

The heavy metal band - made up of James Hetfield, Lars Ulrich, Kirk Hammett and Robert Trujillo - are big fans of Eddie Munson’s (Joseph Quinn) rendition of their 1986 track in the final episode of the Netflix sci-fi show's fourth season when he and Dustin Henderson (Gaten Matarazzo) are deployed to lure and distract the demobats out of the Upside Down to ensure Steve, Nancy and Robin’s safety.

After the last two episodes dropped, they wrote on Instagram on Tuesday (05.07.22): “The way The Duffer Brothers have incorporated music into ‘Stranger Things’ has always been next level, so we were beyond psyched for them to not only include ‘Master of Puppets’ in the show, but to have such a pivotal scene built around it.”

The band also gushed about the “final result” of their song being used in the show - which is set in the 80s and features stars such as Winona Ryder, David Harbour, Finn Wolfhard and Millie Bobby Brown - and Joseph’s guitar skills.

They added: "We were all stoked to see the final result and when we did we were totally blown away… it’s so extremely well done, so much so, that some folks were able to guess the song just by seeing a few seconds of Joseph Quinn’s hands in the trailer!

"How crazy cool is that? It’s an incredible honour to be such a big part of Eddie’s journey and to once again be keeping company with all of the other amazing artists featured in the show.”

Their comments come after Kate Bush thanked 'Stranger Things' showrunners the Duffer Brothers for propelling 'Running Up That Hill' to the top of the UK charts after her 1985 single featured in the fourth season.

Kate said: "By featuring Running Up That Hill in such a positive light - as a talisman for Max (one of the main female characters) - the song has been brought into the emotional arena of her story. Fear, conflict and the power of love are all around her and her friends.

"I salute the Duffer Brothers for their courage - taking this new series into a much more adult and darker place. I want to thank them so much for bringing the song into so many people’s lives. (sic)"
