You might try La Traviata. It has been done in many variants and on many media. Most of the productions, even the less successful ones are beautiful.

One of the good things about the Amato company is that, if you wish to really learn about opera, you can walk in and volunteer. If you have a decent voice of your own, it is likely that you will have a role, if only as a spear carrier, right away. They are a demanding group, though. To be really involved, you have to take part in teaching and outreach for them. Amato, by the way, only does Italian opera.
