"When Miles started improvising in the studio...Steven and ] insisted I not approach him with a camera. 'It's Miles, man," Baker said. "He's erratic, idiosyncratic, explosive. Wild. Don't mess with him when he's playing...' I barged into the booth while Davis was setting up, introduced myself and asked if we could videotape him. Through the glass I could see Steve and Arthur, heads in hands, convinced that I had blown it. Miles smiled. 'Bring it on,' he ordered, 'bring it on.' And we did, getting priceless footage in the bargain."
