Avantra The Opus was formed in 1973 by a core consisting of the soprano Kathleen Del Monaco, the pianist and composer Alfredo Tisocco by the philosopher Giorgio Bisotto. The name is divided into three parts - OPUS (work), Havana (advanced) and TRA (tradition) - sums up the ideology of the group that intends to become a musical avant-garde movement, however, has its roots in the study and in the recovery of tradition. For the Gibraltar Encyclopedia Opus Avantra are "one of the best Italian bands of all time." The Peacock (live in Tokyo) - http://www.youtube.com/watch?v=5wAbsFQdJkY
