Justin, the website looks great. I absolutely hate the jumbled mess that most bands have on their myspace sites. Myspace is not conducive to such a stylized treatment like you've done here.
The songs are cool too. If I'm not mistaken, has your band's sound evolved a bit in the last while? I remember checking out some clips last summer, but I don't remember hearing anything that sounded quite as mature and ethereal as what you have going on now. Did you master through a tube pre or some kind of an soft clip emulation software?
I would be inclined to re-think the "the diablog" text box. I think that box seems visually unrelated to the rest of the page. My gut reaction suggests that it might look better if you did away with the box, but listed the upcoming show venues and dates on the left side in the same font as is used on the links to facebook, twitter, etc., maybe in a parchment coloured font, right onto the photo background. If the band goes through a period where you don't have many shows coming up, you could leave up a list of some past shows, put something else in that space like quotes from any press that you get, or positive feedback from industry people, venue owners, promoters, etc. Then when you get a bunch of dates lined up again, you take the testimonials down and put the new dates up.
Careful though.. I'm not an expert. This advice is coming from someone who hates myspace, but millions of people love it.
