Birmingham’s city centre jags around the site where the manor house of the De Birmingham family once stood, though little now remains even of the great Smithfield livestock market that the 19th century threw down in its place. There’s a summer funfair there now, but in the second week of July the Birmingham Opera Company used the space to stage Michael Tippett’s radiant, hectic opera New Year. A few rides were already disputing the territory with the vast tent erected for the opera, but then Tippett’s drama is devoted to wrestling with the erratic, crammed juxtapositions of modern city life in a spirit of both relish and agony. I caught the exhilarating and rigorous production a week after polling day had falteringly swept Keir Starmer’s Labour to the conundrums of power.
