Published by Timothy Arliss OBrien (A0.1012643). This aggressive cello duet was composed after many bouts of rage with myself. These bursts of anger haunted me for years and only after composing this piece was I freed of my anger. I still listen to this piece from time to time during bouts of rage to remind myself that the only way to win a fight is make concessions and come to an agreement with yourself. I hope these melodies will relieve your aggression and leave you humming this tune anytime you are frustrated. This beautifully fitful piece was performed and recorded by the cellist Raúl Andueza in June of 2020.
