I was expecting some flash, seeing all the lines and stuff, lol. Maybe a little too spaced out, it appears as though you have just randomly placed stuff. I would have expected another black border to create a centered layout, but I didn't see one, change around the black border from the left to the right hand side. Furthermore I think you should reduce the gap between the main content area and the speakers. I thought there would be a navigation there seeing as none was on screen. Reducing the gap would bring the navigation up into 'non-scrollable' view, if you get what I mean. Also you may want to differentiate between what is actually the site and what is the background, it will give it a more organised feel.
Some flash animation would really suite it,
some "waves" coming out of the speakers etc.
I'm not sure if I like the colors, but they are ok.
Good luck!
