“The Bowery! The Bowery! They say such things and they do strange things,” began an 1891 song. But what was once known as Skid Row, full of vagrants and artists alike, has over the past few years continued on a path toward full gentrification. Much has changed from the days of towering bank headquarters and performances by Vaudevillian legends. Progress, to be sure, always brings about change. But while many of the residents of luxury rentals in the Bowery see innovation as being productive, they are also fighting to keep the flavor of this iconic neighborhood’s past intact.
