I wonder why ENO has invested in a new production of Berg’s Lulu, when the previous one, which we first saw in 2002 and then in 2005, was so brilliant as to be virtually definitive. (Of course, that last word is anathema to operatic ‘creative’ teams, for obvious reasons.) Not that this new one, directed by William Kentridge, isn’t good too, though it is excessively busy, compounding the hyperactivity of the score and action.
