4.1 + Definitely a curiosity that adds depth to Eno's rich and varied output. Revisiting this, I'm struck by the tone. One would think ambient music for an airport would be more cheerful. But then I wonder how that upbeat music would make me feel personally if I'm running to my gate towing luggage. Instead Eno creates a sense of calm empathy. As if to say: "I know traveling can be hard. But you'll get through it. Be strong." Also, this album has a vaguely East Berlin feel to it - particularly, "2/2" feels like I'm drifting through rows of gray residential buildings on a sunny day.
