Biography

What particularly impressed was the way that Leroy-Calatayud made space for individual instruments and voices to shine. He would take down the level to allow a softer voice to be heard, allow the brass to come in with a subito fortissimo that would have satisfied Wagner, then take it straight down to make way for a woodwind solo. It’s the first time I’ve heard this conductor and I want to hear more.
