The formation of The Revivalists was all about chance, but everything since then has been a combination of hard work, awesome music, and friendship. The septet has been playing nonstop since 2007, crafting a genre-hopping sound that rounds out traditional rock instrumentation with horns and pedal steel guitar and mixes the divergent backgrounds of its individual members with the humid, funky undercurrents of the band’s New Orleans home. The result is like English spoken with an exotic accent: familiar, yet difficult to pin down.
