As an oldtime Zawinul convert, I really appreciated the article too. "Bitches Brew" was my introduction, and with Weather Report I knew I was listening to an original - "Mysterious Traveler" was my musical bible. But what's nice is hearing these stories about what a great guy he was too. I never had the opportunity to read much about him while he was in Weather Report. I saw them live 3 times; he never said anything, and had that intense, stern countenance on stage that the writer referred to. I've seen videos of him with The Syndicate and he seems to have really loosened up!
I urge anyone who hasn't heard this man's music to go out and get it now! Probably the easiest access point is "Heavy Weather" - if you like that just start investigating.
I will miss him terribly.
