It's been quite a week for youth and the vernacular in the world of so-called “classical” music. Multiply by four the seven fledgling stage animals currently firing up John Adams’s “earthquake-romance” in London's East End, add an orchestra of 13-to-24-year-olds from four continents, student dancers, amateur choirs young and old and just a handful of professionals, and that's only the starting-point for this hair-raising, goosebump-inducing, 500-strong performance of what many of us believe to be Bernstein's most cohesive masterpiece.
