As its title implies, Bartók’s Concerto for Orchestra turned every section of the orchestra into a soloist. From the very opening moments, the ensemble showed that it, too, could play with almost supernal delicacy, as well as making the most of the earthier moments. Salonen balanced everything precisely while allowing youthful energy its head: in the third movement, Bartók takes a dig at Shostakovich by toying with a phrase from his Leningrad Symphony. There can have been few raspberries fruitier than that blown here by the trombone.
