John Williams: A Composer’s Legacy
In our last episode, we followed composer John Williams from his childhood to his 1970s run with Steven Spielberg and George Lucas. Now, we pick up the story as John enters an era of seemingly impossible success… from Raiders of the Lost Ark to Home Alone, Jurassic Park, Schindler’s List, and beyond. In this episode, we explore how John revived the grand orchestral score, conquered the classical music world, and crafted melodies that millions of people can instantly recognize. Along the way, journalist Tim Greiving reveals the habits, quirks, and creative brilliance of this living legend. Twenty Thousand Hertz is produced by Defacto Sound.

John Williams: A Composer’s Life
John Williams has written some of the most famous film scores ever, from Star Wars to Indiana Jones to Jurassic Park. But before the blockbuster success, there was a kid growing up around jazz musicians in New York, and a young composer trying to find his voice. In this episode, journalist Tim Greiving takes us through John’s early life and career, from his years as a session player to the meeting with Steven Spielberg that changed everything. Along the way, we unpack the stories behind John’s early iconic scores, including the two-note terror of Jaws, the symphonic world of Star Wars, and the mysteries of Close Encounters of the Third Kind.
