the Hasidic community. After Chabad shluchim Gavriel and Rivka Holtzberg were murdered in a 2008 terrorist attack in Mumbai and their two-year-old son Moishe was saved, he wrote the song A Letter to Moishe'le. He was part of an all-star group of Jewish musicians who produced a musical tribute to Sholom Rubashkin after the latter's conviction in federal court in 2010. Following the 2011 murder of Leiby Kletzky in Brooklyn, he released a ballad called "Leiby Forever" and a seven-minute music video depicting home movies of Kletzky growing up. "The Big Event" controversy In February 2008, a large amount of publicity was generated for a concert at Madison Square Garden's WaMu Theater in New York City featuring Schmeltzer and Shloime Gertner, under the playbill "The Big Event".
