To be honest I'm not sure I get what you're after and I don't think this would fit it anyway, but I was listening to Scout Niblett when I read this, and looking at some of the bands you like I thought it might be worth mentioning her.

Do want music with a whole lot of things going on in each song and really audible mixing of styles and relatively complex sound, or are you interested in music that has a lot of influences and isn't constrained to one style but is still basically just some guys with guitars (or whatever) and a bit simpler?
