Episode's summary

Erik Satie’s music is everywhere: in advertisements, coffee shops, and elevators. His iconic compositions like Gymnopédies have been streamed millions of times and become staples of background music worldwide. But Satie’s relationship to "background music" goes far deeper than simply having a knack for writing it. Over a century ago, he began composing what he called "furniture music" – pieces designed to fit into an environment just like a table, or chair. It was the beginning of a background music revolution, paving the way for everything from Brian Eno to Muzak. In "Satie’s Furniture," contributor Craig Desson tells the story of why Satie created furniture music, and how his radical idea transformed the way we listen today.
