The search for Enrique Granados’s lost opera, Maria del Carmen, has been a career-long obsession for US scholar, Walter Clark. Written when the Spanish composer was in his early thirties, it got lost as his fame took off.
Granados was killed when a German torpedo stuck his ship in 1916. The score was sold by his sons to a New York collector during the Spanish civil war. Later, it was reported to have perished in a warehouse fire. The diligent Clark kept looking.
He now has a full score and Spanish opera houses are eager to put the work on stage. More here.
