I was just recently watching a video i downloaded of Weather Report, They're playing Black Market in Stadthall Offenbach. Where that is. And there's a part where Zawinul is doing a run on the keyboards, but growing up playing piano, I realized. He's going left and the notes are getting higher, what the hell? Is there anyone else who has noticed this? Oh wait sorry, He has 3 keyboards infront of him. He plays the chords on the lower keyboard, and it's the middle one that he is playing...backwards. Can anyone help me on this?
