A one-night-only glimpse at a new play in which big things happen. As playwright Kevin Kordis explains it, “An unexpected death upends the worlds of angels, demons and many exalted beings in between. Particularly affected is Lucifer M. Star, whose journey through the stages of grief for a friend he had thought immortal ignites a pursuit for the truth behind what really happened, even if it means literally bringing hell up to heaven.” Director Allison Choat and a cast of nine bring it to life. Information is here. (For a theatrical step up from staged reading to radio play, check out The Post-Meridian Radio Players’ “Tomes of Terror: Lenore,” a reading of Poe’s classic poem and three disturbing tales of ghosts, death and revenge for $15 at 8 p.m. Friday and Saturday at Responsible Grace Church, 204 Elm St., near Davis Square, Somerville.)
