Launched by a stirring call to attention Mozart’s brilliant Haffner Symphony marked a big departure for the period. The finale, which Mozart requested be played “as fast as possible” bubbles over with comic-opera vivaciousness. Mendelssohn’s musical Hebridean postcard conjures up the grandeur of Fingal’s Cave, the swelling of the sea, the light on the water and the fury of the waves breaking on the cliffs. Mendelssohn’s clear joy in evoking the soul of Italy is present throughout his Fourth Symphony. Extroverted from the outset, conjuring up sunny skies and radiant landscapes in a virtually flawless assembly of airy and fiery dances, it never lets the excitement lapse for a moment.
