I picked up the DVD Miles Davis,
Live at Montreaux Highlights 1973-1991 a few weeks ago, and Jo Jo is one of the real highlights from 1989 (The video above is actually from a different festival).
Davis is 63, with a band of hot-shot musicians mostly less than half his age. The thing I love here is his face-to-face hand-on-shoulder interaction with Foley McCreary (playing a bass strung with guitar strings). Davis' bands weren't just a case of "take your turn to solo", this is direct transmission from master and student...
I saw this band at around that time in Hong Kong. Which was great, but unfortunately at the time I had little appreciation that I was seeing one of the geniuses of the 20th Century...
