Silence. Near-darkness. Oozy weeds of orchestral strings twist in the mind of Edward Fairfax Vere (John Mark Ainsley), remembering the tragic events of 1797 when he was Captain of the HMS Indomitable. From that awe-inspiring start through to one of the most upsetting of onstage murders, perhaps the greatest parade of major and minor chords in all opera and beyond to some kind of redemption, Michael Grandage's Glyndebourne production - his first in the operatic sphere - of Britten's grandest opera moves with a simplicity and grace which fit this tight little craft of an opera house very well indeed. It's the singing and the orchestra in perfect balance which packs the punches, rather than any one idea in the staging, but that's not necessarily any defect.
