Grande Orquesta Navarre — pianist Sara Parkinson, double-bassist Susan Cahill, bandoneon and cello player Evan Orman, and Tom Hagerman of DeVotchka on accordion and violin — mostly performs classical pieces. But the group manages to find fascinating selections that fit its lively and versatile performance style. When it played Baur's Listening Lounge last December, the Orquesta's unamplified performance enhanced the intimacy of the show. Grande Orquesta Navarre takes relatively obscure classical music, infuses it with tango and delivers it in a cabaret-style presentation, making it exciting again. In an era when everyone has seen and heard everything, this foursome feels fresh.
