Anna Lapwood compares recordings of Benjamin Britten's Four Sea Interludes and picks a favourite. When Peter Grimes premiered in 1945 it immediately put Britten, uniquely among his compatriots, in the first rank of the world's opera composers. As well as the consummate solo vocal and choral writing, the orchestra, too, plays a vital role in Britten's dark drama of alienation and hypocrisy in a small Suffolk fishing community. Several purely orchestral episodes sometimes punctuate, sometimes push forward the narrative and four of these were published separately as the Sea Interludes. Much performed and recorded, Britten's dazzling orchestration vividly conjures up Dawn, Sunday Morning, Moonlight and a Storm.
