A Class Act, Porchlight Music Theatre at Theater Wit, through Oct. 7. It has taken an unconscionably long time for this Broadway musical about the life of A Chorus Line lyricist Edward Kleban to reach Chicago. Luckily, Porchlight Music Theatre has found an amazing leading man in Bill Larkin and a super-talented cast. SCM
Idomeneus, Sideshow Theatre at the DCA Storefront Theatre, through Sept. 23; Iphigenia 2.0 at Next Theatre, through Oct. 14. Trojan War myths have inspired two contemporary plays about warfare and its aftermath, the first German and classical in form, the second decidedly U.S. and hip, but use choral episodes in the Greek tradition and are forcefully presented. JA
Skin Tight, Cor Theatre at Red Orchid through Sept. 25. The line between frolic and fighting is never more finely drawn than in this sweet and fiery tale of bucolic romance from the land Down Under. MSB
Susan Swayne and the Bewildered Bride, Babes With Blades Theatre Company at Lincoln Square, through Sept 22. The adventures of a Victorian "lady detective" include the athletic spectacle you'd expect from an all-female fight troupe, but Reina Hardy's play also exercises our brains with its commentaries on gender issues and intolerance.
