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.

The Apollo Chorus has been performing Handel's Messiah since 1879 and they have it nailed. Singing through the 53 Bible passages Handel set to a Baroque score 250 years ago, it becomes quickly clear - three numbers in - as the choir sings its first part, who owns this performance: it's the Apollo Chorus. Performing and recording steadily through the years, this volunteer singing body is professional caliber. And largely as a result, this is a very satisfying Messiah - just right to kick off the holiday season. 

By the time the Apollo Chorus goes at it, we have heard the opening Sinfonia by the 28-piece orchestra assembled for the performance. The orchestra has all the essentials required for a strong Handel's Messiah: trumpeters ("A Trumpet Shall Sound"), timpani (essential to the Hallelujah Chorus), an organist (a fundamental underlay for the majesty of Handel's masterpiece); a harpsichord (like the organ, this is the house instrument at the Harris, built for Barbara Gaine's Music of the Baroque ensemble); and 20 string players, with Jeri-Lou Zike leading as concertmaster among the five first violinists. 

At this point we have also heard from tenor, William Hite (a Senior Lecturer in Voice at U. Mass in Amherst and frequent opera performer), the first of the soloists (in the recitative, "Comfort ye my people" and the air "Every valley shall be exalted.") He knows how to sing the part. 

The 120-member chorus then rises to its feet for "And the glory of the Lord shall be revealed.") It is signature Handel, and signals to the audience these singers both know the music, and know how to they want to deliver: purposeful and strong, with tightly controlled volume, and clear expression and phrasing. They are consistent throughout 

For those who have listened often to the Messiah, there are markers for style and quality: the tempo (is the Messiah to run fast or slow); soloists: will the basic trio of bass, tenor and soprano by joined by a mezzo-soprano, contralto, alto, or the increasingly popular countertenor? Will they use 18th century period instruments?

Messiah geeks go further, for example, stressing over the expression by singers and players of the ornamental grace notes that bring the trilling associated with baroque music in general. These free-form music indicators are subject to interpretation. 

The Apollo Chorus has made the choices that provide its audience with an accessible, enjoyable and up tempo Messiah, crisply delivered in a rapid 2 hours and 50 minutes including one intermission (and a five minute delay about 20 minutes in as latecomers were seated.)

Conducted last night by Steven Alltop, this Messiah also saves the fidgety members of audience from what can seem an interminable sitting for those who aren't regular baroque listeners.) It's fitting considering Handel wrote the piece from a libretto by Charles Jennens in just 22 days. 

We'll note that once in a while the spaces between passages seemed a bit too short. At certain points the silence between airs and recitative functions like a palate cleanser for the ear.  

The chorus sings with clarity - bring to mind the 300-member Mormon Tabernacle Choir. Apollo Choristers enunciate the language.   

The prominence of the chorus contrasts with the soloists, each skillful, but not making for a natural ensemble. Bass singer Sam Handley, a graduate of Lyric Opera's school, whose background indicates he is trending as an opera performer, warmed as the evening progressed. In his opening with "Thus saith the Lord of Hosts" he seemed a bit tenative - the Harris is a space that takes some adjustment for performers -  but by the time we reached the air "The trumpet shall sound," Handley's individual sections were generating excitement for this listener. (They say he leaves audiences "panting for more.")

Amanda Majeski has the volume and baroque technique down cold, and presented the soprano role in the Messiah with great strength. (She is a frequent performer at Chicago's Lyric Opera, where Majeski's work is described as  "shattering, star-making performance."

Likewise, Elisa Sutherland sang very well, in fact, with more warmth perhaps than Amanda Majeski. But she was certainly struggling with volume - and as a consequence the audience could not hear her well. Owing to this, when concertmaster Sikes accompanied her, the violin performance was in danger of overshadowing Sutherland. Being close up I can attest that she sang wonderfully, if too quietly for the space.
