Tennessee Repertory Theatre’s intriguing 2013-14 lineup includes Oscar Wilde’s The Importance of Being Earnest, John Logan’s Red and Stephen Sondheim’s Company, all of which will present their singular challenges. But before any of that, the Rep makes a little history by opening its season with the world premiere of an original work by Nashville’s own Nate Eppler — in this case a think-piece that was workshopped through the Rep’s own Ingram New Works Project. Eppler, of course, has already made a name for himself as a versatile writing talent, with previous Music City mountings of his plays Sextape and Long Way Down, plus various lighter works, including Southern Fried Nuptials, running through Oct. 6 at Chaffin’s Barn Dinner Theatre. Larries offers a mind-bending exercise: a “multiverse” in which one spouse encounters multiple incarnations of the other. The cast is an impressive mix of accomplished locals, including Amanda Card, David Compton, Geoff Davin, Shannon Hoppe, Tony Morton and Bobby Wyckoff.
