I'm making a powerpoint investigating differences in right hand technique between Fritz Kreisler and Jascha Heifetz. However, I have not been able to find much footage or even live photographs of Kreisler playing, only posed portraits and a few frames from a silent film. Are there any other violinists of Heifetz's generation whose playing styles and techniques were recorded and considered to be Kreisler-esque? Or can you find any live footage of Fritz Kreisler's violin technique?
Tip: don't search his violin technique, search his name. Edit: For more violinists of Kreisler's era (1910s/early 20th century), George Enescu, Romanian composer
