To celebrate the 20th anniversary of creative work as an improviser, on the ground of his artistic and philosophical concepts Mazur prepared solo project – comprovisation (composition for improviser) with electric bass guitar referring to rock music, free improvisation and listening as a cognitive practice called „The Great Tone has no sound – Da Yin Xi Sheng (Laozi – Daodejing)”. In the project Mazur explores the listening as a cognitive practice based on philosophical daoist concept of music joining traditional Chinese and contemporary theories with sound activities and heavy rock vibrations.
