In Sevilla in 2000 I saw some kind of bullfight. It was during a flamenco festival they have every 2 years. It was called a Andalucian Opera I think, it was a story about a young man who wants to become a bullfighter, so there was some signing and some bullfight (2). One of the bulls was killed by the main character while he was on a horse, that was pretty spectacular. I liked it a lot despite the fact that I am a part time vegetarian. Let's just say that I understood why the bulls they kill are black, that way you don't see as much blood.
While we talk about bulls, if you ever go to Sevilla try a tapas of Rabo de Toro, you get the eat part of the tail of a bull. It was really good.
