Cavos is celebrated in Russian musical history as the man who composed an opera Ivan Susanin (1815) 20 years before Glinka. The plot, based on an episode from Russian history, (set in 1612) tells the story of the Russian peasant and patriotic hero Ivan Susanin who sacrifices his life for the Tsar by leading astray a group of marauding Poles who were hunting him.
He was a son of the director of the theatre "La Fenice" in Venice Alberto Giovanni Cavos. At the age of 12 Cavos composed a cantata to celebrate the arrival to Venice of Leopold II. At the age of 14 he obtained the place of the organist at St Mark Church.
In 1797, together with the Italian operatic company "Astariti", he came to St Petersburg. The company was soon disbanded, but Cavos entered the service of the Imperial Theatres, at first as composer for French opera troupe with the responsibility to write music to the operas-vaudevilles
In 1803 Cavos was appointed as the Kapellmeister of Italian and Russian opera and, furthermore, obtained the place of teacher of singing at the Saint Catherine School. In 1811 he occupied the same place in the Smolny Monastery.
He was involved in a massive operatic project: the opera tetralogyRusalka (The Mermaid, also known as Dneprovskaya Rusalka or Lesta, dneprovskaya rusalka (1803-1807, first given in St Petersburg) based on the German romantic-comic piece Das Donauweibchen (The Mermaid of Danube) by Ferdinand Kauer (1751-1831) with the new Russian text by Nikolai Krasnopolsky and Prince Alexander Shakhovskoy (1777-1846). Cavos, together with Stepan Davydov, (1777-1825) provided the additional music to the opera.
Cavos acquainted the Russian public with the opera's by Luigi Cherubini, Étienne Méhul, Carl Maria von Weber, and others. He conducted the first performance of Glinka's "Ivan Susanin" (A Life for the Tsar) in 1836, twenty years after the first performance of his own opera on the same story (though with a different ending). Cavos generously admitted that Glinka's work was musically superior.
Cavos spent more than 40 years in Russia and died in St Petersburg.
His two sons, grandson and other members of the Cavos family, all well known musicians and architects, made a notable contribution into the Russian culture of the 19th century.
