This work is a major contribution for the extremely rare body of works for choir and bandoneon. This composition was inspired by selected passages from "De rerum natura", by the Roman poet and philosopher Lucretius (c. 99 BC- c. 55 BC). In some sections, he offers expressive tirades on the habits of thought and behaviour that he observed in his contemporaries, particularly in what he saw as differentiating the human tendency to destructive delusions from the philosopher’s contemplation and pursuit of understanding of the universe. I felt his impassioned rhetoric immediately resonating like the verses of Discépolo’s tango "Cambalache" (1934)–another literary milestone in the uncompromising portrait of civilization’s persisting afflictions. The work is composed for chamber choir and bandoneon obligato. My choice of the bandoneon for this composition seeks to farther highlight the alternations between gutsy critique and the contemplative disposition. The extended work is presented in six movements, including an interlude before the final section to allow the choir to position around the audience.
