Inviisible should be the band animation. You could set it up on a simple stage. For animation I recommend all low poly figured because the hi-res ones will take much longer to render out. You could mix live with 3D in the background. I've been listening to your tunes, you guys rock. So you may want to go with something that is either heavy metal or do a super hero theme.

I think super heros would suit you guys.

My faves would be Inviisible & Bulletproof , their catchy.
