Friday night's beautifully crafted St. Paul Chamber Orchestra program, heard at Wayzata Community Church in Wayzata, was a nice opportunity to hear artistic partner Thomas Zehetmair both conduct and play violin, along with the viola of his wife, Ruth Killius.
The highlight was their rendition of Mozart's Sinfonia concertante in E-flat major (essentially a concerto for two solo instruments), a masterpiece among masterpieces.
In the orchestral opening, a cascade of ravishing melodies, Zehetmair and Killius played as members of the ensemble, their backs to the audience, until they turned around and dazzled.
Mozart gave the soloists equal weight and Zehetmair and Killius played as one, trading off the melodies and then playing in perfect accord.
The intensity of their relationship was reflected in the intensity of their playing: It was endearing the way they enjoyed each other. They produced an alternately warm and brilliant sound, each seeming to inspire the other through lush legato and pyrotechnic virtuosity. The cadenzas were a special treat.
The orchestra was equally spellbinding, playing with flair and a textbook lesson in Mozart style.
Before this, Zehetmair and Killius played a duet without the orchestra, "Three Sketches" for Violin and Viola by Heinz Holliger, designed as a companion piece when they play the Mozart. The intense miniatures range from a breathtaking perpetual motion, a seemingly endless cascade of notes, to a Cantique, where each instrument played two voices, with the performers humming to complete the six-part harmonies.
The curtain-raiser was the brief "Pastorale d'été (Summer Pastorale)" by the French/Swiss composer Arthur Honegger.
