Two works by R.Straus need mentioning:Death and Transfiguration--and the trio and duet from the last act of der Rosenkavalier.
Other favorites of mine are the Bailero from Songs of the
Auvergne (Canteloube), sung by Kiri te Kanawa; Deux Arabesques (Debussy), for piano; and the Humming Chorus from the second act of Madame Butterfly (Puccini).
The Gorecki Symphony mentioned above is his #3,
nicely performed by London Sinfonietta with soprano Dawn
Upshaw.
