In his 1998 book, “Outliers,” author Malcolm Gladwell makes the case that if you want to become an expert at something — playing or composing music, for example — all you need to do is put in 10,000 hours of diligent practice. No genius required. Writing two decades earlier, playwright Peter Sheaffer took a diametrically opposite view. Sheaffer’s play “Amadeus” explores the counterpoint between a profligate, besotted, irresponsible and ultimately, brilliant Wolfgang Amadeus Mozart and a dedicated, diligent, deserving and ultimately forgettable Antonio Salieri, contemporaries in the court of Viennese Emperor Joseph the Second. Madison’s Strollers Theater is mounting a production of Amadeus, opening Friday, June 2nd at the Bartell Theater. Joining Eight O’Clock Buzz host Brian Standing in the studio are director Kathleen Tissot, and actors Matt Korda who plays Salieri and Sean Langenecker, who plays Mozart.
