Though I loved her music and her voice, I knew little about the celebrated Queen of Disco, Donna Summer - before seeing the Broadway in Chicago show about her. Summer: The Donna Summer Musical tells it all, an engaging narrative spiced with the diva’s great music, beautifully performed.

Musically, Donna Summer was distinctive from other techno-driven disco singers when she burst on the scene in the late 1970s. Her music had a spirit to it, an emotional depth, a poignancy suggesting a trapped soul yearning to escape and express itself.

In Summer the stage musical at the Nederlander in Chicago, her songs are set against the arc of her life. Three singers play her at various points: Alex Hairston is the younger Disco Donna; Dan’yelle Williamson is the older Diva Donna; and Olivia Elease Hardy, “Duckling Donna,” plays scenes earlier in her life. 

Donna Summer wrote or co-authored many of her hits. Not every song is sung in total (though many are) - but we hear enough of each one to be satisfying, and to advance the action. Of course not all her hits would fit in the show - which is one hour and forty minutes with no intermission.

We hear the incomparable "McArthur Park" cover - the first release that fulfilled her ambition to be more than a just disco queen. We hear “She Works Hard for the Money” and learn it was the completion of a contract obligation as she left her old studio for a better agreement.

Reared in Boston, third of seven children in a close-knit, nurturant family, she was the irrepressible performer, the ham, always putting together shows with her sisters performing and her family as audience.

As a teenager, she cut school to audition for a new musical, Hair - and was cast in the Munich production. (Her first single was "Aquarius," was recorded in German.) She found her way into another German recording studio on the strength of a demo track - where she was later discovered by another recording studio on the strength of a demo song, “Love to Love You.” From there she entered the wild ride of the pop star career - but Summer kept a level head. 

As the show recounts it,  "Love to Love You" got her branded as a “Disco Queen,” a label she resisted at first. She always wanted to be a full-range vocalist. But the gates to fame and fortune beckoned, and she walked through them. 

We follow her home life - two husbands, both German, the second one Bruce Sudano, a bass player who fathered two of her three daughters. Played by Steven Grant Douglas, his duet with Alex Hairston as Disco Donna dancing within his guitar strap to "Heaven Knows" is a delight. 

This show is not a typical jukebox musical. Unlike Carole King, Tina Turner or Cher, the inspiration for Summer on stage passed away (from cancer, at age 44, in 2012.) Instead of a living legend, she is now legendary. And Summer the Donna Summer Musical at Broadway in Chicago will give you an appreciation of her life, well lived, through her songs, well sung. It runs through Feb. 23 at the Nederlander
