Hamburg Symphony Orchestra at Roulette

From NYTimes.com:

Everything about Messiaen’s “Des Canyons aux Étoiles” (“From the Canyons to the Stars”) is vast. This audacious 100-minute work is scored for 44 individual instruments, including all manner of percussion, and features a formidable solo piano part. It was inspired by Messiaen’s 1972 visit to Bryce Canyon and Cedar Breaks in Utah, where he looked in awe at craggy rock formations and reddish-orange geological vistas.
