I don't think that light from outside is going to be an option in the places I will be shooting this. There are likely to not be any windows at all as it is going to be done in band rehearsal rooms. Have you seen any of these places? I've spent a significant portion of my life in them and they are almost all windowless horrible dumps (or at least the ones my band practices in :-)) So, I don't think the mixed lighting can be avoided completely. I'm going to do a bit of reading about this colour balance business. All your comments have made me a bit more aware of the issues involved in this.
