John Adams’ 2005 opera explores the personal and moral issues surrounding the invention of the atomic bomb. Captured live in concert, it has colossal power and conviction. At its center is Gerald Finley’s commanding performance as Robert Oppenheimer, a scientist wracked by doubts. Having sung it at the premiere and many times since, he produces a magnificently characterized creation. Julia Bullock, Brindley Sherratt, Samuel Sakker, and Andrew Staples are all superb in supporting roles and Adams himself draws virtuoso playing from a truly galvanized BBC Symphony Orchestra. A major recording of a modern operatic classic.
