The Calder Quartet has been juicing up its Metropolitan Museum series of Bartok string quartets with musicians from outside the classical world. David Longstreth performed some Dirty Projectors tunes with them earlier this month, and Czech violinist-vocalist Iva Bittova is their guest tonight. Born in 1958, Bittova is a uniquely fascinating figure who, like Bartók, takes profound inspiration from the folk songs of Moravian Slovakia. The old ways burn bright in her fractured, ghostly cadences. The Calder Quartet perform Bartok’s second and sixth quartets; Bittova joins them for Moravian song arrangements by Leo Janacek (as heard on her 2004 album Moravian Folk Poetry in Songs) and to explore the sorts of otherworldly improvisations featured on ECM’s Iva Bittova, released earlier this year.
