Éclairs sur l'Au-Delà...

Éclairs sur l'Au-Delà... (Lightning Over the Beyond... ) is the final completed work of the composer Olivier Messiaen.

Scored for a very large orchestra of over a hundred players and unusually lacking a solo piano part, it was written from 1988 to 1991.

The weather event has the light, representing Jesus, and links to space and astronomy — two of the three threads in the 70-minute composition.

Expression of theological ideas from the Catholic faith, and an often ecstatic intention, are characteristic of the composer.

Messiaen's sole visit to Australia was during the Australian Bicentenary in 1988, during the period he was writing Éclairs.
