It was first performed at Sadler's Wells in London on 7 June 1945, conducted by Reginald Goodall and was the first of Britten's operas to be a critical and popular success. It is still widely performed, both in the UK and internationally, and is considered part of the standard repertoire. In addition, the Four Sea Interludes were published separately (as op. 33a) and are frequently performed as an orchestral suite. The Passacaglia was also published separately (as op. 33b), and is also often performed, either together with the Sea Interludes or by itself.
