Bring in the gels, fair studio hand and don't hold back. Last shot these chaps at Electric Ladyland Studios in NYC in their live room, but I gotta tell you it didn't go great - purely down to using an A Head and an S Head in the same pack. They sync at different speeds and therefore inconsistently, thus screwing everything up much to my complete ignorance and frustration - plus only having an hour I could do nothing to sort it. Sorry Yeasayer, I travelled a long way to fail you that day but I hope this addresses that.
