There's a lot of discussion about whether you should be a good live band or a good studio band. I think you can use the studio to make a great "studio record" and not necessarily have to reproduce exactly that on stage, but still be a great "live band." Having said that, if what you're going for is just the raw capture of your live sound, then that's cool, too - go for it! I enjoy working in the studio, though, and while I try to get near to an approximation of what's going on onstage, it's not my first priority usually.
