Just noticed this on Peter Losin's excellent Miles Ahead site:
Another installment in the Bootleg Series (May 1, 2022)
After many stops and starts, the seventh set in the Miles Davis Bootleg Series will be released this fall. It will comprise unissued studio material from 1981-1984, plus the first official release of the full concert from Montreal's Théâtre St. Denis, parts of which were included on Decoy. In addition, the Montreal concert will be released separately on two LPs for Record Store Day.
According to Losin there's a recording from the bowl in '82. I saw him there on a double bill with Gil Evans around that time. I was disappointed that Miles didn't sit in with Gil's band. (Nor Gil with Miles.) If it was '82 I'd seen both of them previously and had liked them better: Gil in Paris in '78 and Miles in Montreal with the 2nd great quintet in '64 or '65.
