Here's my attempt to put in order Angela's appearances. The database can be improved and it will be, in time.
Many opera houses and concert halls don't have archives so it was difficult to gather information.
If you're willing to help, please let me know.

Besides the date/place/title I also added the rest of the cast, orchestra, conductor, chorus, direction, costumes and other pieces of information I consider important.
There are also links, videos, concert programs and photos (see the highlighted words). Scroll to the right to read everything.
