The sixty-seventh classical recording: #694 Peter Warlock - The Curfew
There's some melancholic to this collection of songs, with its use of strings and an eerie flut, sung with short phrases that give you time to contemplate. It feels set at night (although that's unlikely with the birds referenced) and has this gloom over it. It's not an unpleasant one, just contemplative and quiet, and it worked well to get me relaxing and focused.
