Fritz Kreisler (Austrian, 1875–1962) was a beloved violinist and composer. From Wikipedia: One of the most famous violin masters of his or any other day, and regarded as one of the greatest violinists of all time, he was known for his sweet tone and expressive phrasing. Like many great violinists of his generation, he produced a characteristic sound which was immediately recognizable as his own. Although it derived in many respects from the Franco-Belgian school, his style is nonetheless reminiscent of the gemütlich (cozy) lifestyle of pre-war Vienna.
Eduardo Vernazza (Uruguayan, 1910–1991) recorded his impressions of the world’s great musicians, singers and dancers in brilliant, deft sketches made during live performance. He developed some of sketches from pencil to lithograph with even greater intensity of bravura, calligraphic line. The lithographic sketches offered here were made in the 1930s and early 40s.
