The one hundred and fourty-fourth classical recording: #582 Arnold Schoenberg - Erwartung
Erwartung is a one act, short opera for an orchestra and a single soprano. Notably, it never repeats itself, which really added to the complexity of the piece. It doesn't build themes it comes back to, but its economy of storytelling means it doesn't have to, instead it can rely on continuing to tell its story - it can have its complexity because of its brevity, which is a nice compromise. It's a short, sad piece that was lovely to listen to.
