[2] He lived most of his life in Crowley, where in the late 1930s he played guitar with several Cajun bands, including the Four Aces, the Rice City Ramblers, and the Daylight Creepers.

[3] In the 1950s he began to record swamp pop artists, including King Karl, Guitar Gable, Warren Storm, Rod Bernard, and Johnnie Allan, among others.

[2][8] In 1952, Miller wrote the lyrics to "It Wasn't God Who Made Honky Tonk Angels" (an answer song to the recent Hank Thompson hit "The Wild Side of Life").

Miller produced Harpo's "I'm a King Bee" and "Rainin' in My Heart", significant swamp blues recordings later covered, respectively, by the Rolling Stones and by Neil Young.

[11] Although he claimed to be a segregationist, Miller nonetheless used interracial studio bands during the Jim Crow era, when black and white musicians in the South were not permitted to mingle onstage or elsewhere in public.
