The new traditionalists of the klezmer revival, Luminescent Orchestrii — a "small ensemble with orchestral intent" — play a danceable and/or sultry miscellany of gypsy/tango/klezmer/punk, with the Vagabond Opera throwing in their experimental circus music and Eastern European drinking songs to kick things off. The bill tonight encourages even two-left-footers to get up and cut rugs, but if you absolutely refuse, you can still sit back and enjoy the spot-on musicianship.
