A freewheeling, mix-and-match tone was established in the opening set from Frank London's Klezmer Brass All Stars, who stoke klezmer songs with the rowdy oompah of Balkan brass bands. They were joined by Maracatú New York, a Brazilian-style percussion group that overlaid swinging samba atop the oompah - not quite a mesh, but a cheerful collision - and by the eight-woman Hasidic-style vocal group Kol Isha.
