A friend of mine just loves this piece of music. When it was performed a few years ago by the Baltimore Symphony, he went to every performance. He is the one who clued me into this recording. He wore out his LP of it, he played it so much.
Renee Fleming has gotten good reviews singing it in concert and on CD, which is noteable since Ms. Schwarzkopf is her teacher. Fleming has recorded it with Christoph Eschenbach, which is a great modern recording choice for audiophile sound quality.
