Chiming in with a vote for Gone Missing. I was lucky enough to see this Michael Friedman-scored revue at the Barrow Street Theater in 2007. Devised by The Civilians, the show was simple, lovely, and moving.
I consider it a minor miracle that a cast album was recorded. The strong reviews probably made that possible.
The recording captures the wistful, plaintive score wonderfully. I'm linking below to the song "Stars" (posted with permission by The Civilians).
