It was a bitterly cold February night, just about the worst of the winter, when Anne Azéma, Deb Rentz-Moore, Jane Sheldon, Shira Kammen, and Tom Zajac gave one of the hotter concerts of the Camerata season. Love and dalliance in medieval France were the subjects, and the audience, undeterred by frigid weather and by the ecclesiastical architecture of First Lutheran Church, rewarded the “Game of Love” cast with a standing ovation at the end. The church acoustics gave a nice sheen to the voices and instruments on the master recording made by WGBH, and on Valentine’s Day thousands heard the Camerata’s passionate music over the airwaves and via the internet. And a few days later, Anne and Shira inaugurated a new early music series in New York City’s currently “in” venue, Baryshnikov Hall, with some of the same French music heard in Boston.
