Éclairs sur l’au-delà… is the latest great work composer by Olivier Messiaen. Commissioned by the New York Philharmonic for its anniversary, this astounding masterpiece could never be heard by its creator, who died a few months before the premiere. Involving a giant orchestra, this piece could rarely be recorded, though it encapsulates Messiaen’s aesthetics, with its mystical visions and evocative sense of color. Simon Rattle’s hypnotic rendition is undoubtedly one of the greatest.
