I actually really love the production on Toto's Africa as it happens. It's a great example of a vocal sitting perfectly in a mix.
How about "Don't Give Up" by Peter Gabriel with Kate Bush. Fantastic sounding track, and really stood out in the 80's for its warmth.
I also love the production on Talking Head records, particularly Remain In Light, Speaking In Tongues and Stop Making Sense. I didn't appreciate the bright, open sound of them when I was younger, I was just focused on their wacky groove. But over the last few years I've come to notice it.
