The Revolutionary Snake Ensemble is costumed funk/street beat improvisational brass band based in the Boston area performing a unique blend of original and traditional second line brass band music. Led by saxophonist Ken Field, a longtime member of the modern music ensemble Birdsongs of the Mesozoic, the group's colorful costumes and creative arrangements have earned it invitations to entertain audiences as large as 20,000. Revolutionary Snake Ensemble performances have included many venues including: the New Orleans Krewe of Muses Mardi Gras Parade, Kennedy Center for the Performing Arts, the Cambridge River Festival, the HONK! festival, Regattabar, the Central Square World's Fair, the Somerville Theater, First Night Boston, First Night Providence, First Night Fall River, the Boston Museum of Fine Arts, the Brooklyn Academy of Music, the Puffin Cultural Forum, Tipitina's (New Orleans) and the Berklee Performance Center.

The Ensemble can be heard on Parade of Numbers, an animated counting piece regularly aired on the beloved children's program Sesame Street, since the early 90's. It was animated by Field's late wife Karen Aqua (1954-2011).
