The name 'Modzitz' to most is synonomous with "Nigun".
The Modzitzer Rebbe, Reb Yisroel Zt"l was one who had the unique power of Kiruv thru song.
On Yomim Tovim thousands would come to Modzitz to hear the Niggunim song in the Beis Medrash of Modzitz.
The Rebbe zt"l published his sefer Divrei Yisroel during his lifetime.
The Rebbe zt"l used to say "When I hear one singing I could determine where he is holding in Yiras Shomayim".
His Yahrtzeit is on the thirteenth of Kislev.
Yehi Zichro Baruch!
