Just finished Choirs... really amazing stuff. It felt very other-worldly, and I loved the use of saxophones and violins. I enjoyed it much more than Bath, which was still an excellent album, but Choirs cranked everything up a notch--more atmosphere, more layers, and just so much more to explore and allow myself to feel immersed in. There were so many genres and styles incorporated into it, but they all felt natural and threaded with each other to allow for coherence.
Wayfarer stuck out to me the most, and The Antique is probably a close second.
