WARWICK-On Wednesday night, July 27, the Albert Wisner Public Library will host "Rolling on the River," a concert featuring singer/songwriter Danny Einbender. The concert begins at 7 p.m. in Lewis Park. Einbender will present a program filled with songs and music that reflect the history of the Hudson River. From paddles to paddlewheels, canoes to steamships, the audience will travel with Einbender, who uses music to show how the river shaped the people who came to live along its shores. Einbender performed at his first hootenanny back in 1963. In the early eighties he joined the crew of the Sloop Clearwater, working as an educator, musical director of the Arm of the Sea Puppet Theatre and singing with Pete Seeger as a mainstay of the Hudson River Sloop Singers. In 1989 he was a crewmember aboard the tall ship Te Vega for the first joint Soviet/American Trans-Atlantic Sail for Peace. He has received N.Y.S.C.A. grants to produce his original musical play, "Just a Matter of Time," and to create a music composition curriculum for the classroom along with members of the Hudson Valley Philharmonic. He has shared his song-leading and songwriting skills in workshops with staff from Westchester County Parks, Dutchess and Ulster county schools, The Light House for the Blind, the Girl Scouts of America and with teachers all over the Hudson Valley. His award-winning song, "It Really Isn't Garbage Till You Throw it Away," has been recorded by many musicians and utilized by students, teachers, and municipalities to promote recycling in their communities. He's also performed for audiences that range from nursery schools to nursing homes, from Cub Scouts to MTV executives. In case of rain, the program will be held at Christ Church, 50 South St. in Warwick. Call the library at 986-1047 to register for this program. Funds for this program were provided by a grant from the Federal Library Services and Technology Act and the use of Lewis Park is donated by the Historical Society of the Town of Warwick.
