Updated: There’s an element of randomness to any crowdsourced list, and after this one appeared, more people chimed in with their own favorites that hadn’t been included. I’ve therefore gone in and added a few additional titles that were sent in — including a couple of operas that I personally just plain hated; but this is not my list.

Back in my idealistic teenage days, I passionately espoused the view that it was better, as an artist, to touch one person deeply than to reach a crowd superficially.

I cite this by way of introduction to the following list of contemporary operas. This list is drawn from the on-line comments to my piece “Written on Skin and the problem of new opera,” notably including a Twitter conversation extending over a couple of days that showed just how much energy and interest and hope and passion there is about this topic. As part of my article, and part of the conversation, I asked people to name contemporary operas that had moved them; this list is the answer.

Crowdsourced lists are highly arbitrary. Some people who didn’t happen to read my article or see my Tweets in the last few days might add different names to the list. A couple of artists cited works they had helped create, and some will doubtless quibble with my inclusion of them. Some named living composers; some named deceased ones; and some raised the perennial question of how to define “opera” (“Hamilton” got several mentions as an exemplary and contemporary work of music theater). I don’t know if there’s anything to be read into the fact that this list doesn’t include some names you might expect (Mark Adamo, for one); I did take the liberty of adding Tobias Picker’s “Emmeline,” whose omission I decided to consider an oversight. I almost added Louis Andriessen’s “De Materie,” a self-styled “non-opera,” but decided to leave my own tastes out of this. This certainly isn’t my list: I didn’t like all of these operas myself, nor do I think they’re all free of the issues I cited in my original piece.

That’s all beside the point, though. This list isn’t definitive: it’s simply inspirational. It’s a list of new operas that meant something to at least one person: moved him or her to tears, or to excitement, or to a desire for another hearing. We’re talking about an art form that’s struggling with its scale, and many mainstream houses are faced with filling 2,000 seats or more for each performance; it’s hard to find a work that’s going to please that many people. But all of these operas, old and new, large and small, worked for someone — and on some level I still believe that is one significant criterion of success.
