For more than four decades, Simien & company have toured across more than 40 countries and performed over 9,000 concerts worldwide. Their groundbreaking educational program, Creole for Kidz and the History of Zydeco, was developed 25 years ago to introduce K–12 and college students to Creole culture and zydeco’s rich history. This dynamic live performance and companion study guide have raised the cultural IQ of more than 250,000 students, teachers, and families around the globe.

Simien’s music has been featured in multiple major films, and the band has made numerous on-screen appearances. A career highlight came when zydeco music was featured in Disney’s The Princess and the Frog—the first Disney film to feature a Black princess. Simien collaborated with the legendary Randy Newman on the film’s zydeco song and was thrilled to hear the word zydeco spoken on screen for the very first time in a Disney production. In 2024, the band recorded music for the new Disney theme park ride based on the film, now open in both U.S. parks. Disney's massive global footprint has been a game-changer for amplifying zydeco music, a vibrant Louisiana-rooted genre blending Creole and R&B influences, to audiences far beyond the bayou.
