I've long been a KOL fan, both of their old material and the new, and I knew some of their background. What I wasn't prepared for, was finding out so much about the character of each band member, and that Caleb (one of the best voices for years!) would make an excellent subject for a psychologist's study. All of them, and their music, are the product of their background and upbringing, but Caleb particularly. He comes over at times as a very confused man; at times so gentle and sensitive, and at other times, SO angry! The fact that the lads still have the support of their huge extended family and, for three of them, their wives, must help keep them grounded. Such an eye-opener, which had me sniggering one moment, and almost crying the next. Not a lot of music, but that wasn't the point of this documentary. It shows what has made them what they are and, possibly, what they'll become. Brilliant!
