¹ Opera Crosses Over. This musical title, coined as part of Tartu City Day in 2016, refers to a joint concert of opera soloists and other classical music performers, as well as non-opera singers, during which they take themselves out of their comfort zone by dipping into one another’s repertoires – and surprising the audience with the results. Nobody takes themselves, one another or the weather too, too seriously during the concert. The audience normally comprises everyone from genre puritans and dyed-in-the-wool opera lovers to those who don’t really have any feelings about opera one way or the other (well, so far).
