Karl Weigl's music will not be lost. We will return to it after the storm has passed. We will return to those who have written real music. (Pablo Casals) I always considered Karl Weigl as one of the best composers of the old school; one of those who continued the glittering Viennese tradition. He truly preserves this old culture of musical spirit which represents the best of Viennese culture. (Arnold Schoenberg, 1938)
