Finn Wolfhard's band, Calpurnia, shared their debut single last week, and it turns out they're writing lots, too.

In a new interview with Beats 1, Wolfhard talks more about his band's beginnings, love for music—and their ease with writing, too.

“We're all writing constantly. We all have this big Dropbox and group chat of riffs and stuff,” he explains. “We’ve all written a bunch of different new songs hopefully for the next thing. It’s so easy.

“I’m so lucky because it definitely would not be the same way if it was 2006. I just saw a video today of this guy who records all of his music—he made the beats for some of Kendrick Lamar’s stuff—but he records all of his music on an iPhone.”

Listen to the interview in full below:

The band's debut song “City Boy” debuted at No. 23 on the Alternative Digital Song Sales chart. The music news source explains that the song sold 2,000 digital downloads after just two days of sales.

The track is the first single taken from the band's self-titled debut EP, out this spring.

Of course, he’s not the only Stranger Things actor with some serious vocal power. Steve Harrington aka Joe Keery was in the psych rock band Post Animal, who recently announced their forthcoming debut album, When I Think Of You In A Castle. Plus, Gaten Matarazzo (aka Dustin) is proving his musical chops in his band, Work In Progress, who covered Fall Out Boy, Paramore and more.

Not to mention, Noah Schnapp joined Panic! At The Disco onstage back in March for “LA Devotee,” which he happened to star in the music video for as well. And Caleb McLaughlin, aka Lucas, stars in Sia’s new music video, “Santa’s Coming For Us.”

We’re all about these Stranger Things stars and their musical talents.
