drennan: Can you provide some examples of bands or songs you want to sound like? The reason I'm asking is that to my ears, the song on the Kickstarter page sounds quite okay as it is. I can't think of a lot of ways to improve it apart from really basic things such as getting a pop filter for your mic (or even making your own), using EQ on the vocal track to make it sound less muffled, or re-recording takes that have off-key notes (I see you ruled out digital pitch correction).

I just don't see the need for a random group of uninspired session musicians and heavy production here, unless you're actually aiming for a very different style.
