Florence, 1600: Giulio Caccini and Jacopo Peri, two virtuoso singers and rival composers. Striving to rediscover the expressive powers of ancient Greek tragedy, they revolutionized the art of singing and created a new style, which eventually would give birth to opera. In reaction to Renaissance polyphony, these monodies were intended to be sung with the simple accompaniment of a plucked intsrument in order to express the full range of human passions. Peri and Caccini would often accompany themselves but they would also perform with certain family members. Thus brother and sister in this duo follow most naturally a tradition passed on by those great musicians.
