Pauldo,
I was in Dubuque doing the third Rock & Roll Rewind this last week and so join this thread late.
First off, my recordings are typically just a quartet or quintet, so I haven't the experience of a swing band setup.
A friend had a mini-recorder stolen from a club a few years back during his set, and that freaked me out on putting hardware out in the club or hall without an assistant to watch over it. It seems I always wind up doing my recordings gorilla style (no helpers) and so I've gotten used to setting my recorder next to me on stage. I then use an AKG 822 stereo mic on a line I run to the front of the stage. I place my mic in rough proximity to a floor monitor (for vocals) near center stage for the stereo instrument blend. It works for small club/bar settings, and has the added bonus of catching all the little jokes and asides that go on in a club date.
I hope you got to play the date (without needing to know where your towel was)
Mike
