Violin Virtuosos of the 1930s

The period of the 1930s was the first full decade in which violin virtuosos could leave in permanent form their interpretations of the great violin concertos in the improved sound of electrical microphone recording. And record they did, whether they were older established performers like Jascha Heifetz and Josef Szigeti or younger rising stars such as Yehudi Menuhin. We'll sample some of these recordings.
