Singer Iris Oja performs with members of the Tallinn Chamber Orchestra during a rehearsal of the opera 'Nostra Culpa' on April 3, 2013 in Tallinn, Estonia. US composer Eugene Birman turned into an opera a Twitter feud between the Estonian President Toomas Hendrik Ilves and New York Times columnist Paul Krugman who questioned the impact of Estonia’s austerity measures. The short opera in two movements and using two voices will be first performed during Tallinn Music Week on April 7, Birman, who moved from Riga to the US at age of six, told AFP.
