Thanks for the tips. I don't really intend to be recording in this venue again any time soon, but in case I want to affix the camera elsewhere w/ the ultrapod, it's good to know.
I had some problems w/ my last video too (on a tripod), but I think it was because I left auto-focus on and it went a little crazy w/ the lighting, but I'll double check to make sure it isn't happening when the bass is heavy.
