Now you can enjoy an arrangement for two contrabasses. It could be said that different styles converge in the piece, such as romantic, classical Viennese and contemporary. The later perhaps more present in the voice of the contrabass II. It contains certain quite technically demanding passages and a wide combination of sounds, covering different registers as well as different types of sound production.
