The quote 'Friends don't lie' is the creed of 'Stranger Things.' While a TV show, its 'cinematic' legend is driven by the analog synthesizer. Composers Kyle Dixon and Michael Stein used vintage synths like the Juno-6 and the Prophet-5 to create the show's 1980s atmosphere. The pulsating, eerie pads of the synthesizer became the sound of the 'Upside Down.' This choice revitalized interest in analog synthesis for a new generation. The synthesizers provided a sonic bridge between the show's childhood wonder and its supernatural horror. This showed how 'retro' instruments can define the 'legend' of a modern story and the nostalgic weight of its dialogue.
