Another way that you can be a great advocate for opera is to actively support organizations that promote, produce, or perform opera. Here's a list of my favorites (with minimal apologies for my obvious biases). Give them money. Go to see their performances. Share their news with your network.
Boston Opera Collaborative: an organization devoted to developing entrepreneurial artists, who will be the future of opera in America. Their production, Opera Bites, will be performed November 11-13.
Indie Opera Podcast: bringing an independent voice to the opera industry. There are 30 episodes available for your listening pleasure. Enjoy!
Resonance Works | Pittsburgh: a performance organization that not only performs opera, but also chamber music, choral music, orchestral music, and everything else you can imagine at venues across Pittsburgh. Their annual production of holiday favorite, Amahl and the Night Visitors, will be December 16 & 18.
You can also find out what is going on in your area through the National Opera Week calendar of events.
Buy tickets. Invite your friends. Show up. Donate. Support opera.
