Absolutely thrilling. David Murray has more chops and stamina, not to mention ideas, at 60 than most musicians have at 25. I'll add to this, but for now I'll just say that this was a great, long set featuring a beautiful Chelsea Bridge and some bass clarinet work that made Chris Potter's (which I rave about below) look amateur.
I love seeing these older masters well after they've been around the block a few times but before their skills drop off. The combination of absolute comfort on stage and incredible technical prowess makes for the best performance. I was lucky enough to witness it a few months ago with Frisell, Carter and Motian, and it was on full display here as well.
