Here is a theater event that is so rich you cannot be disappointed. Anyone who attends Dynamite Divas: A Tribute to Women in Soul will be richly rewarded by the experience. In fact, it is so good, I would say run, don't walk, to the Black Ensemble theater to see it. (It runs through January 24.)

The premise of the play is self-admittedly thin: African-American multi-billionaire Mr. Maurice (Rueben D. Echoles, who directs, choreographs and designed costumes) has paid $2.5 million to each of four grande dames of soul - Nancy Wilson (Rhonda Preston), Gladys Knight (Rashada Dawan), Roberta Flack (Melanie McCullough), and Aretha Franklin (Shari Addison, a real show-stealer) - who are to spend the day preparing for and then performing in a television special. 

Why just these four? Well, Dionne Warwick, Diana Ross, and Tina Turner were considered - but schedule conflicts kept them away. Besides, these four personalities are probably the only compatible mix, as we discover in the course of the show.

Why put on such a show? Mr. Maurice, who claims to have earned his wealth through his inventions  (e-mail, texting, touch-screens, and Botox!), wants to celebrate the musical accomplishment of these remarkable singers.

These actresses' divas, as personified by these exceptional performers, capture not just the singing style, but also the personalities of their real-life counterparts. And they, too, are mystified by Mr. Maurice's circumstances and motive.  "A black billionaire we've never heard of?"

While the set-up is ridiculous, the music, and the performers, are anything but. In his performance as Mr. Maurice, Rueben Echoles sets the stage with such an abundance of energy, that he truly casts a spell across the audience, forcing the room into a complete suspension of disbelief. That is theater! (And I don't say that lightly, after four decades in the audience.)

Though well paid, these divas - in their 70's - need to be coaxed to sing at first. An extra $50,000 finally breaks the ice, and Gladys Knight lets loose with "I've Got to Use My Imagination," her 1973 hit with the Pips. This offers an inkling of what is to come: Rashada Dawan captures that teary edge to Gladys Knight's voice throughout the night, and replicates the original convincingly - with the added power of being there live.

Now that the audience knows what to listen for, the next plot turn packs a punch using the Assimilator, a kind of holographic transporter used to call up greats of the past. First a phantasm of Billie Holiday alights on the stage and performs, really channels, Holiday's "God Bless the Child" - followed by almost equally powerful impersonations of Dinah Washington ("The Bitter Earth") and Nina Simone ("Mississippi Goddam.")

As Mr. Maurice convinces each Diva to sing - beginning with first hits, and other career high points - the other three sing back-up. Music fills the 299-seat stage for what turns out to be a very short 2-1/2 hour run.

While each of these leading ladies is a powerful performer, and ably capture the singing style and phrasing of their diva, it is Shari Addison who most often seizes control of the stage - befitting her role as Queen of Soul, Aretha Franklin. As the most familiar personality, Franklin gives Addison more to work with. But in McCullough's Flack singing "Killing Me Softly;" or in Preston's Wilson doing the signature "Guess Who I Saw Today," to cite two examples, the stage, and the listeners, belong to those performers.

There are also live performances or video tributes to many other notables - Chaka Khan, Mary Wells, Patti Labelle - the list goes on. Beyonce Knowles also crashes the event, in person, asking why she isn't included in the diva pack, earning a dismissive retort from Aretha: "Do you think they will be singing 'Single Ladies' in 20 years? She also tells Beyonce, "We love your music, at least some of it."

With a rich supporting cast that includes Mr. Maurice's technicians Donald Craig Manuel (as Hubert) and Kyle Smith (as Youngblood), Dynamite Divas thrives on its six-man, all-star band: music director Robert Reddrick on drums, Justin Dillard on keyboard, Mark Miller on bass, Gary Baker on guitar, Dudley Owens on woodwinds, and Bill McFarland on trombone. These guys were versatile and solid as they ran through the years and genre of the divas. Backing Rhonda Preston's Nancy Wilson on "Guess Who I Saw," the performance was "live recording" quality.

Dynamite Divas: A Tribute to Women of Soul at the Black Ensemble Theater comes very highly recommended.
