The two hundred and forty-ninth classical recording: #293 Robert Schumann - Dichterliebe
I feel like it's been a while since I've had a classical recording focus on its vocals, but Dichterliebe really gains its power from it. The love songs in the piece are delicate, here performed with a tenderness that sells it, and having just a piano for accompaniment sells that further. It's simple, but that simplicity is all it needs.
