Child actor Finn Wolfhard has had a big year. The 14-year-old Canadian turned heads in the role of Mike Wheeler, the fearless leader of the rag-tag A/V club gang in hit Netflix sic-fi/thriller series Stranger Things. He will also star in the upcoming remake of Stephen King‘s It, due out this fall. But while Finn is already a successful actor at a very young age, he’s only just scratched the surface of his diverse ambitions in the entertainment industry: he’s also a guitarist, as the world learned last summer when he began to post self-made videos of him playing popular songs on guitar to his Twitter feed, including covers of Nirvana‘s “Lithium,” and Mac DeMarco‘s “Salad Days.”

DeMarco commented on being covered by the young actor/budding musician in an interview with Pitchfork earlier this year, noting “You know, I liked it and thought that it was great. I have texted with him a little bit, and he’s a really nice dude. It’s pretty wild. I like the show, too. He’s so young!”

Over the course of those texts, DeMarco must have invited Wolfhard to join him at a show, because during his performance at Atlanta’s The Tabernacle on Saturday, the This Old Dog rocker invited the young actor onstage to “jam,” even putting him on his shoulders while he played.

Love you maccy boi

Thankfully, Wolfhard’s Stranger Things co-star Natalia Dyer (aka Nancy Wheeler) was side-stage to watch the action unfold, and posted some photos of the feel-good sit-in. Check them out below, via Dyer’s Instagram:
