The boomlet in New York also seems propelled by the desire of young music consumers for something that sounds new and exotic but which you can still dance to in the old-fashioned way — close and tight. That parallels the genre’s evolution in Brazil, where about a decade ago sophisticated college-age urbanites adopted and adapted the old, rough-hewn sound, polishing it into a style now known as “university forró.”

As a dance form, forró is descended from the quadrille, a medieval French style that later made its way to Portugal. “But Brazil being Brazil, it became more sensual in its movements” once it arrived there, said Liliana Araújo, a forró singer and dance teacher who offers instruction before her monthly performances at S.O.B.’s and will also be giving the lesson at Friday night’s Lincoln Center show.

So if you can’t visit the South American country soon do not worry. In the summertime, Brazil will come to you.
