There is an article in today's New York Times about Moshiach Oi! and the "Chulent" gathering in New York. The lead picture for the article shows Yishai in a Na Nach beanie and Menashe Yaakov in an Airan Peleg Na Nach baseball cap, learning Likutei Halachos. As of now, this picture and article are referenced on the front page of nytimes.com
From the article: "To be a hard-core punk band chanting, “Na Nach Nachma Nachman Meuman,” the song of global healing for an obscure branch of Hasidism, is to be something beyond a square peg in a round hole. It is to give up the idea of fitting in altogether."
