Now, in its fourth year, the Red Ribbon Celebration Concert has become an integral part of the world famous Vienna Life Ball Weekend, one of the biggest fund-raising events to further the cause of those living with HIV or AIDS. Staged in the legendary Burgtheater, the concert assembles a line-up of stars which reads like the who is who of classical music. Anna Netrebko, Juan Diego Florez, Piotr Beczala, Elena Maximova, Thomas Quasthoff, Yusif Eyvazov and Kristine Opolais as well as the jazz singer Gregory Porter perform an extraordinary concert according to the motto “Building Bridges for Peace”. From Porter’s hit “Water under Bridges” to a humorous interpretation of Franz Lehar’s “Dein ist mein ganzes Herz” by Anna Netrebko and Yusif Eyvazov, the stars where celebrated with “only bravos” (Salzburger Nachrichten).
