PRG Division Helps Automate “Circus” Tour

Share this Post:

LONDON — PRG’s Scenic Technologies group got the chance to introduce a new overhead automation system and two flying scenic elements when The Circus Starring Britney Spears tour began its European leg at London’s O2 Arena, even though the division received the request to design and build the system only about four weeks prior to installation. Tour producer/director Steve Dixon, production designers Nick Whitehouse and Bryan Leitch, and costume designer William Baker came up with a large circular main stage and two smaller stages, evoking a three-ring circus.

Above the main stage is a large circular truss system, there is a large 360-degree video screen and a red drape, which raises and lowers during the show. There’s also an elaborate automated flying system for scenic elements and performers, including Spears herself.

“PRG was able to deliver the show that we conceived,” said Dixon. “It is unique automation for a concert environment, more like a Broadway show, but with the ability to handle a touring schedule of back-to-backs with eight hours to load in and four hours to load out. With PRG, I now have a slick, smooth automated flying system that is precise, repeatable and most importantly, tourable. PRG is a company that has an absolutely positive attitude. It was never ‘no, we can’t do it.’ If there was an issue, they came to us with solutions. Their focus was on the timely delivery of the system and the costs. They understood the importance of balancing both things.”

PRG engineered the overhead automated flying system on the show including all 15 winches. There is a center lift winch that rotates 720 degrees and works as both a scenery winch and a performer winch. Though this winch is used throughout the production, it plays a key role during two major moments in the show, both of which also include new scenic elements supplied by PRG. The first is when Britney sits onstage on a large umbrella that opens and flies up while slowly rotating as she sings a soft ballad. Later in the show, she steps into a basket-style element that lifts her above a ring of actual fire.

Another key automation sequence in the show involves three large picture frame assemblies that each contain one performer. All three frames revolve in a circle as well as lift and lower. Previously, they only tracked 70 degrees, but PRG engineered a solution that allows the units to rotate 340 degrees around the stage. Three lift winches were installed which are connected via an aircraft cable so that they lock into one another and become a single cable-loop. One revolve winch moves all three frames around the circle and the distance between the frames remains constant.

An essential part of the assignment given PRG was to provide four performer fly winches that the aerialists use with both ring choreography and fabric routines. Here, safety, precision and consistent cue accuracy were absolutely imperative.

PRG Scenic Technologies built permissive switches for each performer winch, which were used by the performer’s individual spotters. The spotter presses a button in order to allow the winch to move up and down. If the button is released, the winch is disabled and will not move until re-enabled (the permissive button engaged). This provided another layer of individual safety for each winch.

The actual control of the winches is handled by a single operator on PRG’s Commander console, the newest version of the PRG Stage Command system for automation control.

The Commander console uses new software and it shares many hardware components with the new PRG V676 lighting console. All of the effects go back to submasters on the control console where the operator can manipulate the time signatures via faders.

There is a grandmaster that can operate all of the effects, as well as individual submasters that control individual winches. Once programmed, the Commander console ensures the speed is going to be the same every night at the touch of the go button.  All of the drive racks and control intelligence for the system were moved to ground level where they could be more easily serviced. This also reduced the weight on the grid and allowed for faster load in and out.

The new control system and permissive button arrangement is particularly appreciated by the lead aerialist, Shannon Beach. “The new automated flying system had a big impact on the production and the feeling of security for the performers who work with it every night,” Beach said. “It’s so tight and so specific, we now feel that we can sharpen and expand our performances. Our confidence in the system allows us to focus on our performances.”

PRG Scenic Technologies’ team, led by Orestes Mihaly, general manager, garnered kudos from Mo Morrison, production executive for the tour. “They were very open to what we required and always had a positive, confident attitude,” he said.

Prior to the tour, Whitehouse and Leitch partnered with Steve Dixon, William Baker and Morrison to form the production company Road Rage, which is producing The Circus Starring Britney Spears tour as well as handling the production design for the current Il Divo world tour.
