“Revolution” released in 1968 reflected the social movements and civil unrest of the 60s. The theme is that true revolution is not based on hatred and destruction. “Revolution” begins with a change inside yourself away from violence and toward peace.

This version of “Revolution” was the first version that was recorded (hence the use of ‘1’ in the title). The single version, which was recorded later but released first, was released as simply “Revolution”. “Revolution 1” was a slower, quieter, and more bluesy track, while the single version was a faster and louder hard rock track with plenty of distortion employed.
