Descripción en Youtube:
The Act I finale ensemble of one of the best Rossini's operas. Amenaide, the distressed soprano, has been unjustly accused of treason, and everybody is intent to force on her as much guilt as possible. Some music from here Rossini later used in his "The Barber of Seville".
Performance from Florence, 2005, starring Daniela Barcellona and Darina Takova in title roles. The full DVD is available under TDK label. Also, I highly recommend the RCA Red Seal CD recording of "Tancredi" with Vesselina Kasarova and Eva Mei, which has 2 endings included.
