Dieter Ammann has won numerous international awards and is now one of the most renowned Swiss composers of his generation. The multilayered unbalanced instability is a concerto for violin and chamber orchestra that seeks unpredictability and shifting perspectives between solo and orchestra. Ammann’s slowly developed orchestral triptych reflects his meticulous working methods. Core reshapes and transcends its improvised origins, while the slowly unfolding Turn serves as an Adagio in the set. The irrepressible energy of Boost forms the kind of dramaturgy of tension and release that led Boulez to describe Ammann’s music as ‘artistic reflected spontaneity at the highest level’.
