"Here's how you bring light into the world," says a scruffy-bearded man in shirtsleeves and a knit cap on a Brooklyn rooftop. "First, you get up in the morning and you scream!" His mischievous grin melts into something more ethereally content as he screams. At length.
He's had plenty of practice screaming — he does it for a living.
The man is Yishai Romanoff, lead singer of the hassidic punk band Moshiach Oi and one of the half-dozen artists, activists, and culture-makers profiled in the documentary Punk Jews.
The phrase can seem like an oxymoron: The essence of punk is to challenge inherited convention, yet adherence to rich traditions of convention is the common through-line of all of Judaism's myriad flavors.
