A piano plays a chord in the silence, and a chain of sound grows, swells, and breaks into passionate, endless song. No question, the great Romantic composers knew how to unleash emotion: whether it鈥檚 Tchaikovsky diving into the whirlwind of a doomed love or Puccini creating melodies to melt the heart. Or, indeed, Rachmaninov uniting a glittering piano and a sumptuous orchestra in a concerto that could have been written for our soloist, Boris Giltburg. 鈥淓very note pulses with life and warmth鈥 was how one critic described his playing, and the same could be said when guest conductor Ludovic Morlot shares Roxanna Panufnik鈥檚 vivid new versions of Alma Mahler鈥檚 neglected love songs.
