No idea, i deleted it after the first hearing.
Then it sounds to me (and doubtless will also do to some others) that you weren't taking much notice at the time of listening. Still, if Schumann doesn't do it for you and Carter does it less, neither fact means that their music is not expressive!
I've already given you a couple of Schumann recommendations, so here's some for Carter that you might like to try:
Elegy for string quartet (1943)
Piano Sonata (1945-46)
Variations for Orchestra (1955)
Symphonia:
Sum Fluxæ Pretium Spei (compl. 1998)
I suspect that you may well find the opening movement of the last of these tough going first time around, but there is an unusually mesmeric, glacial quality to much of the middle (Adagio tenebroso) movement and the delicate gossamer textures and flights of filigree fancy in the finale (Allegro scorrevole) are simply a joy to behold.
Best,
