I can truthfully say the same thing.
But the solo I'm thinking of wasn't at the 18th and Vine Festival in '95 or '96 (yes, I was there). It was about 1990 at the Grand Emporium, of all places. It was a Murray quartet with John Hicks and Fred Hopkins.
They closed with "Mr. P.C." Cyrille played one chorus on every part of the drumset. One exclusively on the snare's head, one exclusively on the snare's rim, one exclusively on the side of the snare, one exclusively on the snare's stand, etc. -- all the way around the set. Each cymbal was soloed on for one chorus with sticks -- then he grabbed each cymbal and bent it rhythmically for a chorus.
When he'd run out of drumset pieces, he beat out one chorus each on his chest, his arms, his hands, his legs.
This display went on for 10-15 minutes. The 12-bar chorus pattern remained clear throughout. The tempo was way up, and he bent it only a little.
Besides being a great drum solo, it felt like a great blues performance too.
