‘Who can turn skies back and begin again?’-PeterThis book contends that Peter Grimes, widely regarded as one of the greatest and most influential operas of the 20th century, is also one of the British theatre’s finest ‘lost’ plays. Seeking to liberate Britten and Slater’s work from the blinkered traditions of theatre and opera criticism, Sam Kinchin-Smith poses two questions: If an opera was created like a play, and can be staged as a play, is it a play? If a portion of its success and influence is the product of this newly identified theatrical engine, is it then a great play?The answers involve Wagner and W.G. Sebald, George Crabbe and Complicité, Akenfield and Twin Peaks. Challenging long-established narratives of post-war theatre history, this book makes a compelling case for why practitioners and scholars of performance ought to pay more attention to Britten and Slater’s achievement – a milestone of unconventional English modernism – and perhaps to other operatic masterpieces too.
