I've seen the Quintet (twice), Octet and Big Band, and it's been excellent every time. Both times I saw the Quintet, Nate Smith was playing (the first time, a few years ago, as a sub, the last time (in March, I think) as the "new guy"). As a sub, he was clearly reproducing Billy Kilson's role, whereas now he is clearly doing his own thing, which is different but will doubtless become just as cool over time.
