Bon Bon Vivant is helmed by front-woman and songwriter Abigail Cosio and her husband, saxophonist and vocalist Jeremy Kelley, whose marriage and creative partnership sits at the center of the band's identity. Blood harmonies from Abigail's sister Glori Cosio round out the group's signature sound, joined by accordion and piano from Ryan Brown and a rhythm section built on sousaphone and drums.
The band's music pays homage to New Orleans' bawdy musical tradition while folding in klezmer, gypsy swing, dark ballads, and up-tempo indie dance rock — a genre-blind sound Cosio's songwriting drives with lyrics as fierce as they are heartbreaking. Named Best Emerging Artist by OffBeat Magazine in 2018, Bon Bon Vivant made its New Orleans Jazz & Heritage Festival debut in 2022 and has continued releasing new music, including the 2025 single “Sin Eater,” while touring nationally and building what the band calls a genuine community around every show.
