Composer Eugene Birman poses during a rehearsal of the operetta "Nostra Culpa" in Tallinn, Estonia, Thursday, April 4, 2013. Inspired by a lively social media exchange between Estonian President Toomas Hendrik Ilves and Nobel Prize-winning economist Paul Krugman, the two expats, Birman and Scott Diel, who wrote the lyrics, have composed an operetta that soars across the merits and pitfalls of austerity _ an ever more prominent reality in Europe’s struggling economy.
