Fascinating that The Who were considered an R&B group early in their career, then transitioned to hard rock. As for Led Zeppelin, I'm amazed that they still had to pass an audition after they released the eponymous Led Zeppelin record (the one with the Hindenberg exploding on the cover). That's got to be one of the best albums of the 1960s, if not in the whole of rock. Looks like the jury was out at that early stage of things, though.
