There is nothing more delightful than a little discord between appearance and reality. The exterior of Chicago’s famed Apollo Theater is modest, but its current show, “Million Dollar Quartet,” packs a zesty and energetic punch. It is hard to believe the magnitude and volume that radiates from within this seemingly small theater.

The show chronicles the famous night during which Elvis Presley, Johnny Cash, Jerry Lee Lewis and Carl Perkins came together during an unforgettable recording session at Sun Records. While the show undoubtedly takes some artistic license, its authenticity is delightful. The play catapults its audience into a world of song but provides some semblance of a narrative so that they are not lost in a sea of musical numbers. Its effect is almost concert-like, though it is wrapped in a rich story.

Elvis Presley is portrayed by the charismatic Brandon Bennett. His energy is impressive, though he often fades into the background while his talented cast members take center stage. This may be intentional, but the show necessitates four equally dynamic performances. Bennett could pay far greater homage to “The King.” The show’s rhythmic energy carries him along, though his performance is a bit of a missed opportunity.

Chicago actress Whitney Kraus Jones takes on the role of Presley’s beautiful girlfriend. While her physical presence is petite, her performance packs an incredible punch. Her rendition of “Fever” is nothing short of mesmerizing and her dynamism lights up the evening. While Bennett’s performance leaves something to be desired, it is rather humorous to witness his female counterpart outshine him many a time.

Chris Damiano’s portrayal of Johnny Cash is nearly flawless. Though his performance is a quieter one, he radiates humility while still delivering jaw-dropping music. He pays true homage to the genius that was Cash himself. He comes across as the gentlest of the four beasts, and his presence seems to constantly balance and neutralize tensions while never fading into the background. His character is genuinely likable; he is a much-needed facet in a show that is packed with so many difficult and diva-like personalities. He imbues the production with a reassuring rhythm that creates a lovely pace.

Lance Lipinski portrays the infamous Jerry Lee Lewis and, without a doubt, carries the show. His representation of the pianist is almost humorously precise, and his technicality is impeccable. His performance is a treat to both watch and listen too; his talent is apparent the moment he sets foot onto the stage. When it came time for “Great Balls of Fire,” the audience was nearly on their feet. He is a master of both the microphone and the keyboard, using them like toys while simultaneously creating incredible music. His energy, at times, borders on stifling but manages to ride the fine line between delightful and overbearing, while never traveling too far in the negative direction.

Shaun Whitley portrays Carl Perkins and comprises another of the weaker links within the show. His character is grounded and is enjoyable to both watch and listen to, but lacks the spark that both Damiano and Lipinski infuse the stage with. The show itself mutes the negative effects of his lackluster performance, though it could have been vitalized on a whole other level if it were stronger.

“Million Dollar Quartet” is an experience as well as a production. The simplistic set provides an intimacy that puts the audience right inside of the recording studio alongside the dynamic foursome. While a show comprised mainly of musical numbers has the potential to fall flat, the Chicago cast breathes inspiring life into it.

The cast has a daunting task at hand, though their portrayals of four of music’s greatest legends are all in all impressive and enjoyable. While some performances are weaker than others, the Apollo Theater’s current show vibrates with energy and provides an all-around good time.

“Million Dollar Quartet” will run through April 28 at the Apollo Theater.
