I said arena, I'm dreaming like 15,000 people all packed into an arena, or just now thinking about it, a theater would be a dream come true aswell.

The largest venue I played was one that held about 600 people supporting a fairly sucsesfull pop/punk band from Argentina, and it was about half full.

But to answer your q? No, while we do have Coliseums and Stadiums they are of much lesser scale that the ones in England and the U.S. for example.
The Rolling Stones are playing at the new Coliseum, which I guess is where BJ would play if they make it here again.It Holds about 18-19,000 people, we have also othe coliseums that hold somewhere between 10,000-11,000 people.
So I guess that's about the largest we have working.
Back in 1987 and 1989 when Bon Jovi made their trecks through here, they played at the Hiram Bithorn Stadium which I guess had more capacity but it was so ****ed up that they are no longer holding any shows there.
