We've believed the split ever since. Groundwater is a music history podcast that follows the current underneath — the blues, running from Congo Square to the South Bronx, from Robert Johnson to Aretha Franklin to hip-hop. Each episode traces a moment the industry tried to keep apart: the soul sessions at Stax and Muscle Shoals that crossed every line; Louis Armstrong working race and commerce from New Orleans to Chicago; the Great Migration carrying Muddy Waters and the Delta sound up the Illinois Central to Memphis, Chicago, and Detroit; and the state's long campaign against the singers who got political, from Billie Holiday to the Dixie Chicks. If you want to understand why American music sounds the way it does, start here and follow the water.","last_synced_at":"2026-09-08T20:18:19.773007+00:00","page_url":"https://stenobird.com/podcast/groundwater-the-blues-beneath-everything-7851197"},"episode":{"title":"Twelfth Street Station: The Great Migration and How New Orleans Music Reached Chicago","slug":"twelfth-street-station-the-great-migration-and-how-new-orleans-music-reached-chicago","published_at":"2026-06-09T09:00:00+00:00","page_url":"https://stenobird.com/podcast/groundwater-the-blues-beneath-everything-7851197/twelfth-street-station-the-great-migration-and-how-new-orleans-music-reached-chicago","show_page_url":"https://stenobird.com/podcast/groundwater-the-blues-beneath-everything-7851197","url":"https://groundwater.fm/s1/4","audio_url":"https://op3.dev/e/media.transistor.fm/61ad9cf9/3412c308.mp3","summary":"The music didn’t ride north on riverboats. It rode the Illinois Central Railroad — out of New Orleans, up through Memphis and the Mississippi Delta into Chicago — in the luggage cars and Jim Crow coaches of the Great Migration. Episode 4 of Groundwater traces what the music became when it left the South: Louis Armstrong stepping off the train at Twelfth Street Station in 1922 with a cornet and a fish sandwich; King Oliver’s Creole Jazz Band and Armstrong’s first recorded solo; the Hot Five’s “West End Blues” and the thirteen-second cadenza that changed what a trumpet could do; Muddy Waters electrifying his Delta guitar on the South Side for Chess Records; Count Basie’s Kansas City swing; and Charlie Parker and Dizzy Gillespie inventing bebop as an act of self-defense. The pipeline begins at Congo Square. The northern terminus is Chess Records.
