Most achingly-beautiful music

Appalachian Spring by Copland recorded by Michael Tilson Thomas and the San Francisco Orchestra on RCA. With a great system the experience in nothing short of fantastic.
Beethoven's Piano Sonata #30 by Wilhelm Kempff on DG. The third movement seems to place us on a plateau rarely visited.
Franz Schubert's Death and the Maiden Quartet by the Takacs Quartet on Hyperion. The music is beautiful and angry, and the recording realizes the tremendous angst of the composer.

Tons of classical pieces but, in the more modern world Jeff Buckley singing Leonard Cohen's "Hallelujah" The first time I heard it I was frozen on the spot and yes, crying. It's an amazingly moving song.

Enjoyed reading this thread. Here are some additions.

1. Spanish Harlem - Rebecca Pidgeon, Leiber, Jerry

2. Harvest Moon - Cassandra Wilson, Young, Neil

3. The Priests (album) by THE PRIESTS

Leslie Mills, "The Keeper".
