Zydeco practitioners like Chris Ardoin and Double Clutchin’ demonstrate that this traditional music genre can be updated without losing its roots. Chris and his drum-playing brother, Sean, may have first learned bouncy Louisiana dance rhythms from musicians like their great-uncle Amede and their grandfather Bois Sec, but on last year’s Turn the Page they’re also influenced by contemporary R&B, hiphop, and funk. The title track finds Sean displaying his finest Boyz II Men falsetto, and on cuts like “Fever for Your Flavor” and “Outro,” he and bassist Dee Greenwood add thumping low-end beats. Chris completes the picture with joyous chants and shout-outs and fast-fingered accordion sonics that cause heads to nod and feet to move. The band performs at a zydeco dance at 8 p.m. at Glen Echo Park’s Spanish Ballroom, 7300 MacArthur Blvd., Glen Echo. $10. (301) 309-0895. (Steve Kiviat)
