John Adams, Hallelujah Junction: Composing an American Life (FSG, $26). A hugely important, exceedingly well-written memoir in which the composer of Nixon in China and Doctor Atomic explains with engaging clarity why he broke with modernism to forge a new, more accessible style of classical composition. Even if, like me, you find it impossible to warm up to Adams’ minimalist music, this book will leave you in no doubt of why it has made so deep an impression on a generation of American composers and listeners (TT).
