What's your favorite "slow" piece?

[bloke]

If in the audience and listening to a slow song or a slow movement or slow whatever piece of music and one doesn't find themselves being lulled to sleep, that's probably a sign that it's a pretty good piece of music.

[Tubajug]

A wonderful piece and a masterclass in orchestration.

[Billy M.]

First time I heard this piece I literally had to pull my car on the side of the road and listen in full and get the piece name.
