I agree that it was the early Weather report that was the best: Weather Report, I Sing the Body Electric, and Sweetnighter are my choices. I saw them in concert ages ago at Wesleyan University in Middletown Connecticut. They played in an all purpose' room with seating on the floor to a crowd over only about 150 listeners. My luck, between sets they mingled with the crowd and I got to talk with Miroslav, Wayne, and Joe Zawinul for about 20 minutes.
Unfortunately at school my room mates would always crack that their music sounded like a bunch of instruments tossed down a flight of stairs so for 4-years as an undergraduate I spent a lot of time listening to them through my headphones.
