Klezmer music traces back to the dance music played by itinerant Jewish music that traveled throughout Europe in the nineteenth century. The tradition is brought up to contemporary standards by Brave Old World, a group that includes members from California, Chicago, New York and Berlin. "The Washington Post' called Brave Old World "the revival's first supergroup. Every player is a virtuoso". "The Boston Globe" explained that Brave Old World "plays a klezmer music that is entirely grounded in the present, so intensely evolved from the music as it was, and, yet, so clearly, obviously, entirely klezmer that one could not seperate out many of the influences".
