Meet the Beatles again—well sort of—in a certified home run for Cirque du Soleil. Before he died, George Harrison persuaded the surviving Beatles (and Yoko Ono) to license the group's music to Cirque. The remixed music by Beatle producer George Martin and his son Giles is revelatory on the state-of-the-art sound system, often like hearing the songs for the first time. Coming up with visuals to match was more of a challenge. Cirque created a theatrical and fanciful version of Liverpool, loosely telling the story of Beatlemania and the postwar generation without literally depicting the Fab Four. It's a lot to absorb, and one's attention can be split between the aerial stunt work and the action on the ground. But that just gives Beatles fans a reason to see it twice.
