It’s true — terribly violent stories make some of the best theater. In 1990 convicted murder and renowned prison poet Jack Unterweger was released due to a pardon, one issued by the Austrian president at the insistence of the Viennese literati. His rehab didn’t go so well, but it usually doesn’t when you kill 11 prostitutes in your first two years of freedom. Academy Award nominee John Malkovich, backed by a 40-piece chamber orchestra and two sopranos, makes his UMS debut as Unterweger’s ghost — sharing striking, delusional and scattered memories in The Infernal Comedy: Confessions of a Serial Killer on October 1. $10-$75. 8pm. University of Michigan, Hill Auditorium. 734-764-2538. www.ums.org.
