The overture to Rossini’s opera “La Gazza Ladra” and Tchaikovsky’s Symphony No. 6 in B Minor (“Pathetique”) exist in opposite universes — the first, a place where confidence and bumptious good humor rules; the other, a cauldron of dark passions and fierce exaltation. What they share, however, is an imperative for urgent momentum. And conductor Christopher Zimmerman and his Fairfax Symphony Orchestra do momentum exceedingly well.
Their program at George Mason University’s Center for the Arts on Saturday opened with the Rossini and ended with the Tchaikovsky, revealing a string section that never let velocity blur its crisp ensemble, a wind section that handled the spotlight eagerly and a percussion section that had a field day in both pieces. Sure, there were moments when the dialogue between strings and woodwinds could have been smoother and others where the cellos could have had more heft. But the spirit of the Rossini was delightful and Zimmerman drove a clearly mapped course through the thicket of the symphony that focused on its architecture and reveled in its contrasts.
