Long-lost Mozart cantata debuts

Lost for over 200 years, a cantata co-written by classical maestros Wolfgang Amadeus Mozart and Antonio Salieri rang out in public for the first time on Tuesday, shedding new light on their reputed intense rivalry.

The Italian composer was allegedly so jealous of the Austrian prodigy that he once tried to poison him - a claim rejected by experts as the collaboration was performed in Prague.

"The part composed by Mozart is, shall we say, more ingenious and dramatic, while the other two verses are more lyrical," musician Lukas Vendl said after playing the four-minute composition on a harpsichord.
