A webpage called Opera Musica has suddenly come into my awareness. If this is old hat, then please forgive me. It focuses on singers, something I'm always looking for. You never have to wonder who is singing.
There is a page of artist profiles with pictures and schedules.
There is a page of operas and concerts, also with pictures and details. They say you can buy tickets through their page, though I haven't tried it.
There is a page of videos of the artists in performance.
There is a page of artist managers.
I will add this to my lists.
