As the English National Opera gets set to move into its renovated home, some big questions have yet to be answered, writes Norman Lebrecht: “The critical public issue for ENO is, as it has been for a decade, the question of identity. The company is not English, except inasmuch as its singers mangle the vernacular. It is not National, lacking the resources to tour. And it is desperately keen to shed the corsets of Opera in the quest for new audiences and fresh relevance. It is, in sum, a product in need of rebranding, a relic of a very different society that has failed to adjust to post-industrial demand.”
