Dare I say the pun? Your site ROCKS!
Overall I found the site to load quickly ( i have highspeed though)
and thru my widescreen monitor it looks very good.
I think your header and footer are great for your site. Don't change it.
Doesn't appear to be too busy or too cluttered.
The only thing I think I would try to change is ( if you even really care to, depends on your standing) is the valid mark up. You are already using a tableless design, and the errors that W3c spit our are quite minor...y not take it to the next level. But again I say depending on your standing, some people round these parts don't really care about valid mark up, and if you don't then I think your site is rockin as is.
Best of success, to you and your bands !
