My good friend Catalin is an amazing musician. He belongs to the « singing double bass » familly, as I think I do. His Kreisler transcription is not easy and he performs it with a nice sound like the violin. This type of transcription played on a modern double bass, easy regulation, solo tuning, bright and warm sound, brings to the musical community the sound of a « cello-alto » as the viola does for the violin. I like it!
