I do this kind of work for a living, and this is based only on my personal design preferences. Don't take any offense, I'm just telling you what I'd tell new clients if they asked for an opinion.
The overall color is a little dark, and the gradient thing is not especially hip anymore. With the right colors and the right degree of gradient change, you can make it work, but it generally tends to look amateurish and old, if that makes sense.
I'd use a more subtle border between your site body and content box.
I'd make the header a little taller so you can get more impact out of your band name and/or, especially, your header slogan. I like the slogan and if I were designing your site, I'd make it more prominent - at least as noticeable as your band name, if not more.
I'd make your menu links a little bigger - they're almost lost due to the small font.
The "biglogo" is, what... intrusive? I'd drop the frame around it and just place into a corner of your content body or place it in the corner of the site outside of the content body. It's a coin toss between using the biglogo or text for the band name - if you have a nice, clean, slightly larger version of a logo (whether biglogo or something else), I'd use that rather than text. Put it out there, baby!
As ACFunk noted, a Contact link or page is essential. When I do sites for small retailers, I put the contact info on every page. No one ever complains that it's too easy to contact you.
Most importantly, don't be discouraged! Building a site can be challenging and frustrating, but you'll appreciate the work once you get it nailed down. And when you have a photo gallery up, I guarantee you'll visit your site at least once a day just to pat yourself on the back. And there's no shame in that!
