Praised by the The New York Times as “a Samuel Beckett for the Jon Stewart generation,” and dubbed elsewhere a “maverick wordsmith” and the author of “loping, postmodern laments about the emptiness, alienation and shit-slog that is modern living,” Will Eno is a playwright to watch. Nashville gets its first look at one of his works as Actors Bridge Ensemble’s “Sideshow” performers, under the direction of Jessika Malone, present Eno’s 2004 Oppenheimer Award winner The Flu Season. The story involves inmates in a psychiatric hospital where love happens — if only as a metaphorical vehicle to advance a play preoccupied with the mechanics of plotting, archetypal characters and evocative writerly tendencies. Yet Eno’s script has also been characterized as “a wistful meditation on the precariousness of human feeling,” so maybe it’s not all verbal pyrotechnics. In the not-too-distant past, The Flu Season invited positive reviews in New York and Chicago, but also scorn in Seattle. Theatrical experiments are usually interesting, but you’ll need to see for yourself how this opus fares under the aegis of the youthful Sideshow folks, as they navigate an unconventional emotional journey. The cast features Michael Redman, Jaclyn Johnson, Ricardo Puerta, Josiah Gibbs, Mitch Massaro and Erin Randolph.
