Okay so I'm a professional, let me start by saying its quite good for a novice, I can get around it, it makes sense, it looks clean and tasteful. I really like the old stained wood texture you have going on. Honestly its better than a lot of pro sites I've seen.
Now for some tips...
Move your nav to either a top horizontal position or the left top corner. or just switch the left with the right collumn. (this is because the eye looks to the top left first, because of the way we read books)
Clean up the cropping/dithering on that guitar, or just scratch it and put like a shadow of a guitar there or something. (its right next to your nav, a really terrible place to have a low quality image)
Give yourself a little more padding on the top between the browser tools and the bands name. (a little empty space does a lot for a design)
change the color of the bands name, it clashes with the green background, and it just isn't bright enough to catch my eye. (the tan you used for the rest of the site would probably look great)
Put borders on the individual pics in the bios (some people don't bother it drives me nuts when people don't)
Space the posts in your blog a bit more.
Kill the hit counter it screams 1995 personal site. If you want to know how many people have seen your site there are better hidden ways that can give you a lot more information.
LAST AND MOST IMPORTANT! You don't have any meta tagging or decent title information, you need to do these things so that search engines find your site. Look up basic
SEO (search engine optimization) meta, title and description tags. If you need some help with this stuff look at the source for some business sites, or PM me and I'll show you some examples.
Overall though, pretty fantastic, beats the hell out of a myspace!
