Codon is a term used in the field of molecular genetics to describe the interaction between the three elements that are important for both the creation and the preservation of life. Kevin Houben uses this term as a metaphor for the interaction between the conductor, the musicians and the committee of a concert band. They all have the same goal, to preserve the life of the band. This work consists of three movements, symbolising birth, life and death - either of a human being or a band. From the foundation of a band over good and bad times up to the optimistic future, this work will appeal to the soul of every band member in the world!
