Opera confronts us with extremes of emotion, sometimes delivering unforgettable, life-changing experiences. Fuoco Sacro (‘Sacred Fire’) seeks out singers who have the power to pierce our hearts, presenting three of them at work in the most intimate details of their rehearsals and preparations. Ermonela Jaho, Barbara Hannigan and Asmik Grigorian are watched closely as some of their secrets are revealed: how they inhabit their roles and transform words and notation on a page into that intangible but powerful magic being communicated to audiences from the opera stage. Over 90 minutes of extras are included featuring vocal warm-ups and live performances accompanied by pianists Evgenia Rubinova, Reinbert de Leeuw and Francesco Piemontesi.
