Chenier & The Red Hot Louisiana Band, Shawn Colvin, Donna The Buffalo, Steve Earle, Steve Forbert, Eileen Ivers, Lucy Kaplansky, Quebec’s Le Vent du Nord, Joan Osborne, Railroad Earth, Toshi Reagon and Subdudes. Joining them are such emerging talents as the Angel Band, Dan Bern, Mike Doughty, Felice Brothers, Sarah Lee Guthrie & Johnny Irion, Rhett Miller, Sara Watkins, and Dala (a young female duo from Toronto, who also star in “Girls From the North Country,” a TV special that begins airing on many PBS television stations this month). Regional artists of note include Jay Ungar and Molly Mason, Milton, Tao Seeger Band, Rick Nestler and The Dirty Stay Out Skifflers, Matt Turk, Hope Machine, The Edukated Fleas, Stout, and the Walkabout Clearwater Chorus.

Produced by and benefiting the Hudson River Sloop Clearwater, Inc., a nonprofit, member-supported organization launched by Pete Seeger and others to preserve and protect the Hudson River and its tributaries, the festival celebrates environmental activism and education. It features seven stages with live music and performance artists, a Green Living Expo, riverfront activities, environmental workshops and exhibits, and booths run by educational and activist organizations. The Sloop Clearwater and Schooner Pioneer will also be there during the weekend, affording visitors the opportunity to sail on the Hudson. Roving artists and jugglers, children’s crafts and activities, juried crafts and the Circle of Song (where audience participation is the focus) also are on the docket.
