Technically speaking, Nashville was first locally introduced to this very popular musical in 2007, when Kaine Riggan mounted a production at Nashville Dinner Theatre in Donelson. But while the road-show version now at TPAC may not actually be the absolute local premiere as publicized, theatergoers will in fact witness a more complete, full-bodied effort, with spectacular sets, hundreds of costumes and balanced casting. Henry Krieger and Tom Eyen’s soulful take on the Motown era, with focus on the emotional and professional ups and downs of a girl group that reads suspiciously like The Supremes, first opened on Broadway in 1981 under the late, great Michael Bennett’s direction, and ran nearly four years, winning Tony Awards. Then the show reemerged to much fanfare in late 2006 as an acclaimed feature film that launched the career of Jennifer Hudson. The large cast here includes Syesha Mercado, Adrienne Warren and Margaret Hoffman, with Moya Angela in the pivotal role of Effie White. Other key performers are Chaz Lamar Shepherd and Chester Gregory. The direction and choreography are by Robert Longbottom. Some material original to the movie version only has been reincorporated into this international tour staging.
