The music critic and regular Gramophone contributor Richard Bratby has just published a history of the Academy of Ancient Music, Refiner's Fire, the first book telling the story of a period-instrument ensemble (Elliott & Thompson; £25).

James Jolly spoke to Richard about the book, about its charismatic founder and long-serving Music Director Christopher Hogwood, and about how a substantial recording contract with Decca'a L'Oiseau-Lyre label – masterminded by the producer Peter Wadland – shaped the ensemble's style and approach.
