I agree with carbro, joana. The Ballet of the Wiekci Theater has a reputation in Europe and has an interesting repertory. But is almost unknown in the US. Anything you can tell us about the performances you see would be much appreciated. And it's possible that others, reading your reports, will be encouraged to chime in.
I'll be back in Warsaw in early October, but there doesn't seem to be a schedule availble for then. Last time I saw Traviata. I enjoyed the production and loved the theater very much. Maybe this time I'll be lucky and there will be a ballet. Something BIG, full-length, involving the entire company and all its resources. That's my wish, at least.
