Worth a listen
Here is something of a rarity: one of my favourite sopranos (Elisabeth Schwartzkopf) singing one of my favourite operatic arias (Marietta's Lied from Korngold's Die Tote Stadt). (In the original opera it's a duet, but it's more usually heard in concert as a soprano solo.)
I first heard this aria (and indeed first heard of the under-rated opera from which it comes) when it was used in the Bruce Beresford segment of the film Aria. A good film, if patchy: last time I looked only available on Region 1 DVD.
