Mendy Werdyger (born 1959, Brooklyn, New York) is an American Hasidic Jewish singer, songwriter, and owner of the Jewish record label Aderet Records and its retail store, Mostly Music, on 13th Avenue in Borough Park, Brooklyn. In 2010, he released his fifth studio album. He is a son of the famous hazzan (cantor) David Werdyger, brother of popular Jewish singer Mordechai Ben David, uncle of singer Yeedle (Mordechai's son), and father of singer Yisroel Werdyger, also known as Sruli Werdyger.
Since 2005, Werdyger and more recently his son Meir have been working on audio restoration of old albums. Though he lacks a college degree or professional training in sound engineering, he has re-mastered four CDs worth of songs recorded by Cantor Yossele Rosenblatt, using computer software to clear off the scratchy distortions on the original records.
