It's incredible to hear what opera singers can do with their voice. They also need to have great acting skills.
I love Anna Netrebko. Not only is she a beautiful, charming lady, but also a great singer and actor.
My favourite male opera singer at the moment is Spanish tenor Rolando Villazón. He's also a very funny guy.
I have seen a lot of operas here in Vienna and also some in the Arena di Verona. From the Verdi operas, I love Nabucco and La Traviata the most. In general, Puccini is my favourite composer. But I also love Carmen.
I listen to opera a lot, not only whole operas, but also duets and arias from various artists.
It also depends on my mood, like classical music in general. Sometimes I spend weeks without listening to any opera or classical stuff, then again I spend some time only listening to that.
