MARGARETVILLE — From Arturo Toscanini to Joan Baez, musicians of every genre have been influenced by the Catskills. Soprano Gina Hanzlik will celebrate that heritage in an eclectic concert Saturday, July 26 at 7:30 at the Margaretville Methodist Church. "A Memoir of Margaretville" will follow the Birthday Block Party on Main Street (4-7 p.m.) to conclude the village's Sesquicentennial Celebration. Joining Gina will be Grammy-nominated violist Anna Stromer and pianist and recording artist Dan Meinhardt. There is a suggested admission donation of $10.
