When I started playing solo 10 years ago, I had some ham-fisted idea about trying to subvert the "singer-songwriter" tag/genre, and I tried to obscure my identity into the identity of a collective or band or whatever. That's part of the reason that I used to play with backing tapes and why so much of my early stuff was so awash in tape hiss and echo noise.
Ted LeoThere'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.
