One of the most "fly by the seat of your pants" gigs a recording engineer can pick up is that of recording a live show. Even if you know the band, the venue, and the folks running the production there are always unexpected circumstances that can pop up. This can be both supremely frustrating and supremely satisfying to deal with. Either way it is always interesting. Whether you are looking to do live multitrack recording, or just trying to record your set at the open mic, if you stick to a few simple rules (check after the break) you'll end up with a decent product.
