Locatelli's rarely performed concerto "The Harmonic Labyrinth" is named after its extraordinarily expansive cadenza. YuEun Gemma Kim will bring her dazzling technique to this piece, equally matched by ABS flutist Sandra Miller's definitive performance of Bach's Orchestral Suite for flauto traverso and strings. Elegance is at the foreground of Telemann's Concerto and Quartet. And Bach's merry and bright "Wedding Cantata" sets the stage for this Sunday matinée.
