If you’ve never been fortunate enough to get a ladies’ choice dance to these guys, know that the Creole String Beans are the city’s best wedding band, which of course means they’re one of the country’s best. That’s really what they keep their focus on despite their solid originals, which must mean that they either a) like to keep themselves humble or b) know that covers of obscure swamp pop don’t necessarily get you on the radio. The CSB are out there spreading the gospel of Crescent City soul nevertheless, making it feel fresh and free and actually meaningful while giving mawmaw good memories of her prom.

What’s unique about the Beans’ melange of New Orleans musical history is what’s left out: no trad jazz, no gypsy jazz, no klezmer, just the sound of a highly influential rock, R&B and soul scene that started at the Dew Drop Inn and petered out at Jazz City Studios. They do for boogie-woogie, New Orleans piano, swamp pop and Gulf Coast soul what other great party bands like the Boogiemen do for ’70s party R&B. The Sacred Heart CYO Dance, in other words, come back to life: the straight jump of “Let the Money Drop” (money dance!) and the proto-soul of “Hotline Baby” (with a Fess intro) and even some rockabilly and ska for variety.

Those are just the originals, too: Here’s Smiley’s “Someday” and Dorsey’s “Holy Cow” and some obscure Aaron, Brother Ray and Tommy Ridgley. Their originals are so in the pocket you don’t even notice the occasional clunkiness of the lyrics—okay, maybe on the Fats-style shuffle of the title track. But so what? Weddings are celebrations, not poetry. And celebrating the nation’s most historically underrated rock ’n’ roll scene? That’s one you wanna respond to.
