I know I've mentioned it here before, but playing with a gypsy jazz group can really help one get comfortable at extremely fast tempos. No drummer to fall back on. We did the Hawaii International Jazz Fest on Sunday, and the great saxophonist Dave Choy was a guest with us. The first tune was "Dark Eyes", which eventually winds up at an insane pace. After we finished, Dave turned around and said "You guys are crazy".
I had a funny experience last night. We were playing a club gig. You know how sometimes people bang silverware on tables, ashtrays, etc., trying to play along? Usually it's just flat out irritating, a distraction. Anyway, we were playing at a really fast clip, and some guy starts whacking on the table with his butter knife, just for about four bars, and very tastefully and at a perfect volume, perfect swinging time. He was just doing it distractedly, not even really aware he was doing it, I think. Afterwards, I went over to say hi to him, and he says "Hi, I'm Les DeMerle". I just cracked up... suddenly, it all made sense!
