Absalon Crash is a composition for cymbal and live electronics. Homage to Søren Absalon Larsen. A cymbal is equipped with a piezoelectric sensor and a transducer. They are connected through a custom-built effects pedal to form a feedback network. A performer acts on the system to explore different sonic worlds. The performer shapes the sound by using her/his hands on the cymbal to muffle or suppress certain frequencies from the resonance spectrum, and by adjusting the settings of the effects pedal. Absalon Crash fits in the tradition of electro-acoustic works exploring the resonant characteristics of physical materials, like David Tudor's Rainforest.
