I’m not a hippie. I have more than just a passing affection for lip gloss, and tie-dye gives me vertigo. But seeing the Kansas City Repertory Theatre’s performance of “Love, Janis” made me want to not wash my hair for a month and smoke Camel Reds. “Janis” opened last month, christening the KC Rep’s new Copaken Stage at 13th and Walnut in the H&R Block building. Night after night, Kacee Clanton, Mary Bridget Davies and Lena Kaminsky have been giving the kind of performances that would’ve made Janis scream. Well, more than usual. Clanton and Davies trade off nights on lead vocals while Kaminsky embodies Janis’ raw soul in her fiery monologues. The night I went, Clanton literally brought the crowd to our feet with her exacting portrayal of Janis’ music and fervent performance style. “Love, Janis” closes April 1st, but if you can make it there — start running now. If not, the Copaken Theatre is a must-see itself. And you can do just that when the The Syringa Tree opens April 27th.
