The fourth classical recording: #3 Guillaume de Machaut - Ballades
I'm not sure I got the exact right recording for this, but I am not sure it matters. These songs are somewhere between a troubadour style and more sacred hymns, drawing inspiration from both - I suppose where the ballad form starts off. It's very pleasant and relaxing, not as aggresive as some earlier recordings were. As impressive as before is the layering, how a song is built without many instruments and by layering different voices on top of each other instead.
