It’s no secret that the music of Stranger Things was inspired by Tangerine Dream, the pioneering German electronic group whose synth-driven scores for films like Sorcerer changed the face of movie soundtracks. It seems that Tangerine Dream were fans of Stranger Things’ homage themselves, as they’ve covered two tracks from the show’s soundtrack in their own style.

The composers of the Stranger Things score, Kyle Dixon and Michael Stein (of Austin band SURVIVE), have previously discussed the influence of Tangerine Dream on their music. “There’s a Tangerine Dream score for Sorcerer that’s great,” Dixon told Rolling Stone, “I've rented that one a few times. The Keep. I think you can only get The Keep on VHS.” The title track of Tangerine Dream’s 1981 album Exit was also featured in episode six of Stranger Things.

Tangerine Dream formed in 1967 and have released over one hundred albums, many of them film scores. The group’s founder and constant member Edgar Froese died last year, but they continued as a trio with keyboardists Thorsten Quaeschning and Ulrich Schnauss, and violinist Hoshiko Yamane.
