In Mendelssohn as in everything else, violinist Jascha Heifetz plays with brilliance and an edgy intensity that impart a feeling of urgency to the music even in its most poetic moments. He brings dazzling technique and heart-on-the-sleeve Romanticism to his searing interpretation, and is brilliantly backed up by Charles Munch and the Bostonians. The recording is spacious, clean, and tonally quite accurate, though Heifetz is a bit closely miked. --Ted Libbey
