Actor Joseph Quinn, who plays a heavy metal fan on "Stranger Things", not only got to meet band Metallica at Lollapalooza, but share a jam session to the song "Master of Puppets" with the band backstage.
Quinn's character Eddie did have a crucial scene with that very track in the show, reports eonline.com.
In a video shared to Metallica's Instagram, Quinn took viewers with him as he met the iconic group.
And while it's safe to say Joseph (and his character Eddie) are fond of Metallica, the admiration is mutual.
In the clip, Metallica vocalist James Hetfield told Joseph he's a "big fan" of the Netflix series, reports eonline.com.
"Have been since season one," Hetfield said.
"My kids and I, it's been a bonding experience for us."
On the topic of "Master of Puppets", Joseph noted that he had the song on repeat for two years.
He added: "I feel very connected to you guys."
The actor became even more connected to the rockers when they asked him "to go jam" backstage.
After shredding on the six-string with the band, Joseph was gifted a red guitar equipped with all their signatures.
Although the 29-year-old teased that he was "a bit rusty," the group was more than impressed.
"You're hired," lead guitarist and songwriter Kirk Hammett joked.
Meanwhile, drummer Lars Ulrich looked at the camera and said: "We'd like to make an announcement. Metallica is now a five piece."
