Lu Watters & His Yerba Buena Jazz Band

Washboard is an early 20th‑century, instrument-defined microgenre of American vernacular music that centers the scrubbed, rhythm-keeping washboard (often played with thimbles, spoons, or brushes) as a featured percussion voice. Emerging from the crossroads of jug-band music, country blues, ragtime, and hot jazz, washboard ensembles typically performed upbeat, stomping tunes, blues numbers, and novelty songs in dance halls, rent parties, and on street corners. The sound is raw and percussive: chattering triplets, scraped backbeats, woodblock and cowbell accents, and improvised breaks punctuate small combos with guitar/banjo, piano, clarinet or cornet, kazoo or jug, and call‑and‑response vocals. Although tied to specific bands and scenes of the late 1920s and 1930s, the washboard aesthetic persisted through folk and skiffle revivals and fed directly into zydeco’s rubboard tradition, leaving a lasting imprint on roots and revivalist music.
