Riffs,
I like the general layout and the colours. The pink / purple goes well with the black background.
What you might want to do, as I have looked at the code, and seen that you have made the menu with tables, is to add a mouseover code, which would change the background of the menu when the user moves over it.
This can easily be done by adding the following code into the <td> tags for the menu....
onmouseover="style.backgroundColor='#CC66FF';" onmouseout="style.backgroundColor='#9900CC'"
Keep going, and add a few video clips, etc, to work out where you want to position them.
But so far, I like the layout - simple, effective and nice colours.
Good luck
Alex
