The festival, a celebration for the Hudson River, features singer-songwriters, performers and musicians offering fun with a purpose – a diverse mix of contemporary, traditional and American Roots music, dance, family-oriented entertainment and storytelling.
In addition to music and dance, a juried craft show, Green Living Expo, working waterfront, environmental education sites, and a "circle of song" featuring audience participation fill out the weekend's schedule.
