On August 29, 1966, the Beatles played what their official site identifies as their last ticketed concert, at Candlestick Park. Sixty years later, that ending can look like withdrawal at the height of the frenzy. It was not. The studio transformation had already begun, and leaving the road gave four increasingly distinct musicians room to push it further.

Start with Revolver, released earlier that same August. It is the pre-retirement proof: longer sessions had already produced greater experimentation before the final tour ended. Paul McCartney, John Lennon, George Harrison and Ringo Starr sound like four instincts learning to share a studio.
Then move to Sgt. Pepper's Lonely Hearts Club Band, where freedom becomes theater. With touring behind them, live reproducibility no longer constrained the music. Finish with Abbey Road, where competing instincts become a frame for pleasure rather than a problem to hide.
The last ticketed show matters as permission to push a lesson they had already learned. Take the route in this exact order: Revolver, Sgt. Pepper's Lonely Hearts Club Band, Abbey Road.
