Its called Nostra Culpa and its a 16 minute 2 act opera dramatizing the exchange on Twitter between Paul Krugman and Estonian President Toomas Ilves about that country’s austerity program.    Robert Siegel interviewed the librettist and composer on NPR yesterday:

SIEGEL: I would sort of have expected you to have written this for a tenor and a baritone. But unexpectedly, for me at least, the two characters – Paul Krugman and President Ilves of Estonia – are both sung by the same mezzo-soprano.

BIRMAN: Right. Well, the mezzo-soprano is somebody I’ve worked with before and she’s, I think, one of the greatest talents in Estonia as a dramatic singer. And my idea – my sort of inspiration to set these words was not so much to make some kind of argument, but to have the singer portray the people themselves who are stuck in this – between these two sides.

SIEGEL: Now, one writer observed that the entire exchange between Krugman and Ilves consisted of a 70-word blog post with chart, and then four tweets. Puccini had a lot more to work with when he sat down to write “Tosca,” let’s say.

BIRMAN: Well, one could write an opera, a full-length two-hour opera, using just this content, in my opinion. Because, in a way, why is the story interesting? To me it’s interesting because we have been discussing this ever since 2008, 2009 – what to do and how to get out of this, and we’re still not out. And the story is being written as we go.

The opera has its debut on April 7 in Estonia.
