Swamp Pop is indigenous to the Acadiana region of South Louisiana as well as from the Beaumont/ Port Arthur area of neighboring East Texas. It is marked by highly emotional, ultra-romantic, plaintive style vocals. The simple, unaffected and often bilingual lyrics are backed by a honky-tonk piano, bellowing sax sections and a strong R&B backbeat. Upbeat pieces often possess the bouncy rhythms of Cajun and black Creole two-steps, and their lyrics frequently convey the local color and joie de vivre spirit pervading South Louisiana. Slow melancholic ballads with their undulating bass line and dramatic breaks exhibit the heart-broken ‘what’s-the-use-of-living’ laments common to many Cajun and black Creole compositions. The genre appeared during the mid-to late 1950s, its heyday lasting until the early 1980s.
