The thankless art of the librettist

Next week, after the première of Mark-Anthony Turnage’s new opera Festen, the cast and conductor will take their bow. All being well, there’ll be applause; and then a brief lull as the creative team takes the stage. There’s often a ripple of curiosity in the audience at this point, because it’s rare that we get to see just how many people it really takes to make an opera.
