If you have a chance before tomorrow, listen to How Slow the Wind and at least some of A Flock Descends..., which should help clarify my paper. If you're intrigued, Les Yeux Clos (The closed eyes) is a somewhat different flavor (for piano) and neat to listen to with the picture open, and Requiem is a much earlier work, perhaps his first masterpiece (Stravinsky approved). La Mer is mostly to refresh our collective memories about Debussy; a gorgeous piece and well worth any time that's not already double-booked...
