NEW YORK (AP).- Brooklyn’s old Bushwick neighborhood has quickly become a new world-class arts mecca with music, dance, sculpture and theater bursting from defunct warehouses and desolate streets where gangs still roam. That hasn’t kept artists away from the affordable, industrial spaces ever more rare in a pricey city. “This was a ghost town, with tumbleweeds blowing down the street five years ago,” says Jay Leritz, co-owner of Yummus Hummus, a Middle Eastern-style cafe on a street filled with musician rehearsal and recording spaces. “The streets were empty,” says Leritz, “and that was the big attraction the lack of rules, like your parents went away for the weekend and it’s a free-for-all.” Born-in-Bushwick creations have reached Carnegie Hall, Madison Square Garden, the Metropolitan Museum of Art and other top venues
