Artpark’s “Wednesdays at the Gorge” free concert series heats up this week, adding spice with a double-bill of world class Zydeco featuring CJ Chenier & the Red Hot Louisiana Band and Nathan & the Zydeco Cha-Chas. The son of Clifton Chenier—the “King of Zydeco” and the first Creole musician to ever win a Grammy award— CJ (Clayton Joseph) has led the Red Hot Louisiana Band since his father’s death in 1987, taking his (and his dad’s) instrument, the piano accordion, to new heights with a combination of musical styles. Nathan Williams (pictured) of the Zydeco Cha Chas grew up in a Creole-speaking Louisiana home and was influenced by legends like Chenier from an early age. Though Nathan is the frontman for the Cha Chas, the band is really a family affair, with Nathan’s brother Dennis Paul Williams bringing his jazz influenced guitar to the mix, along with the keyboard talents of Nathan’s son, Nathan Williams, Jr. A cousin, Mark Williams, plays Rubboard for the Cha Chas, and the eldest brother, Sis “El Sid O” Williams, is the band’s manager. Rounding it out are bassist Robert LeBlanc and drummer Herman “Rat” Brown, formerly of Buckwheat Zydeco.
