Scherzinger’s ravenous performance provides a great part of the adrenaline, but the show is also jolted into new life by the collision of the spartan Lloydiverse with all the plush and purple of Lloyd Webber’s score. Chu described the composer as, in the ’80s, mounting a kind of maximalist coup on musical theater in the name of the operatic notion of primo la musica: “Nothing—neither plot nor character, not social issues, not even good taste—would be more important,” she wrote about his shows, “than what happened when that invisible beam of music shot across the darkened theater into their souls.” Productions of Lloyd Webber’s aspirations to Puccini have long tended to put a hat on a hat. The music throbs and flourishes; so does the stage, loaded up with gondolas and chandeliers, fog and fashion and fur and roller-skates. Lloyd, true to form, runs the other way. He and his collaborators, the set and costumes designer Soutra Gilmour, and the lighting designer Jack Knowles and video designers Nathan Amzi and Joe Ransom, craft a spare, echoing dungeon, girded by towers of LEDs. (This kind of seeming minimalism is its own circus trick, costing as it does millions of dollars.) Inside Gilmour’s vast, deceptively empty box, Knowles, Amzi, and Ransom’s incredible work is, in and of itself, a liquid, high-octane form of scenery. They’ve kept little but the fog.
