Friday was a busy morning for Ruggero Allifranchini, the associate concertmaster of the St. Paul Chamber Orchestra.
Playing one concerto as the soloist, leading another from the concertmaster's chair, then taking the same position for a Haydn symphony — you couldn't exactly call it a quiet day at the office.
Allifranchini thrives on the responsibility, however, and his solo work in Vivaldi's "Il favorito" Violin Concerto was a gem of rediscovery and reinvention.
Standing center stage with a small collection of 16 players around him, Allifranchini probed the outer movements of the concerto with keen-edged musical intelligence.
In the opening allegro, he teased caprice from a series of sharply imagined micro-episodes before unleashing dashes of piquant, mercurial temperament in the scampering finale.
The slow movement was not so much a pause for breath as a rapt holding-in of it. Time seemed suspended as Allifranchini spun Vivaldi's fantastical patterns in the ether above a featherlight accompaniment of violins and violas.
Igor Stravinsky once waspishly noted that Vivaldi didn't write 500 concertos, but "the same concerto 500 times." To which this pulsatingly detailed performance of "Il favorito" was the perfect rejoinder.
Allifranchini's solo contributions were again a feature in the Concerto Grosso Op. 5, No. 12 ("La Follia") by Francesco Geminiani that opened the program.
