When harpsichordist Christopher Hogwood and record producer Peter Wadland founded the Academy of Ancient Music in 1973, their mission was to create Britain’s first orchestra devoted to recording baroque and classical music on period instruments. They went on to change the musical world. Their success brought the AAM global fame – bringing historically informed performance into the mainstream and putting Vivaldi into the pop charts. But then the orchestra faced a new challenge: reinventing itself to survive and thrive in the world its own success had created. For the first time, Richard Bratby tells the story of this trailblazing orchestra and the people who shaped it: fifty years of innovation, exploration and musical adventure, from the pioneering days of the early 1970s to new directions – and new triumphs – in the 21st century.
