In the opening "Nocturne"[of Shostakovich's Violin Concerto No.1] -a seemingly endless weave of melody-Midori produced a sound so still and pure as to make us disbelieve that a bow of horsehair was actually being rubbed against gut strings. Despite the relative quiet of the movement, this is darkly restless music, but Midori had the house rapt in short order.
