On Aug. 1, 1942, the nation’s recording studios went silent. Musicians were fed up with the new technologies threatening their livelihoods, so they refused to record until they got their fair share. This week, Evan Chung explores one of the most consequential labor actions of the 20th century, and how it coincided with an underground revolution in music led by artists like Charlie Parker and Dizzy Gillespie.

One Year is produced by Evan Chung, Sophie Summergrad, Sam Kim, and Josh Levin.

Derek John is senior supervising producer of narrative podcasts and Merritt Jacob is senior technical director.
