These lists always kind of remind me of popular bands that changed music over time. The most drastic "pivot" I've ever come across in a known band is Ministry, who went from a benign new-wave Depeche Mode clone in 1983 [1] to a pseudo-Cabaret Voltaire in 1986 [2], then to full-on metal by 1991 [3].

Others e.g. Bitches Brew (1970), In a Silent Way (1969), are totally different again from these.
