Contemporary blues star Susan Tedeschi, renowned Sixties-era troubadour Arlo Guthrie, and “newgrass” sensations Old Crow Medicine Show are among the headliners for Clearwater’s 2009 Great Hudson River Revival, which will take place on Saturday and Sunday, June 20 and 21 at Croton Point Park in Croton-on-Hudson, NY. The Clearwater Festival will be celebrating a number of auspicious occasions this year, and new festival director Jon Dindas is trimming the sails with a lineup that mixes longtime folk-centric Clearwater favorites like Richie Havens, Jay Ungar and Molly Mason, Rik Palieri, Linda Richards and Tao Rodriguez-Seeger with a bevy of top acts and musical artists who will be making their first appearance at the festival—Alejandro Escovedo, A.C. Newman, Allison Moorer, MacTalla Mór, Elvis Perkins in Dearland, Cornmeal, Dr. Dog and more. The music will run all day, from 10am to Dusk. Get your tickets now—early birds save before May 20.
