I'd never heard of The Passenger by Mieczysław Weinberg. So it was a bit of a shock to see the Holocaust depicted on the ENO stage. Weinberg set the first act to a slow, drone like pace. It moved very slowly - apparently it was to recreate the atmosphere at Auschwitz. Act 2 had more melodies and drama - but ones that were heart-wrenching. Johan Engels's 3-dimensional set design was provocative and well lit by Fabrice Kebour. The rather large cast was exceptional in the delivery of text and conquering the tricky melodic lines. One came out of the theatre feeling unsettled.
