WILLIS PRUDHOMME is one of the few remaining zydeco musicians who can trace his heritage almost as far back as the music itself. The Kinder, La., native, the son of sharecroppers, was himself a farmer before picking up the harmonica at age 45. He switched to accordion and was tutored by Cajun great Nathan Abshire. His soft vocal strains carry along two-steps and waltzes with a measure of understatement that's often overshadowed by the more frenetic zydeco musicians of younger generations, as evidenced on his 2006 release with Zydeco Express, Living Legend. Prudhomme will perform as part of the Atlanta Cajun Zydeco Dance Association's monthly dance series, held Sat., AUG. 23, with lots of Louisiana food and plenty of beverages to ease the sweating that will ensue. $8-$15. Dance workshop, 7 p.m.; dance, 8 p.m. Knights of Columbus Post 660, 2620 Buford Highway. 404-825-9768. www.aczadance.org.
