International opera stars perform for free to raise money for the German AIDS Foundation. Accompanied by the Beethoven Orchestra Bonn conducted by Stefan Blunier, they perform well-known arias spanning three centuries, including Mozart, Rossini and Bernstein.

The opera gala has been organized by the German AIDS Foundation since 2012, making this the 5th event. The profits will go towards projects in Germany and Mozambique. Arts.21 presents the highlights of the gala in two parts.
