Vasks compositions incorporate archaic, folklore elements from Latvian music and place them within a dynamic and challenging relationship with the language of contemporary music. The works are frequently given programmatic titles based on natural processes. Vasks' intentions are however not so much a purely poetic praise of nature or showy tone painting, but rather the pursuit of themes such as the complex interaction between man and nature and the beauty of life on the one hand but also the imminent ecological and moral destruction of the world which he expresses in musical language.
