The baroque opera “Dido and Aeneas” comes at 8 p.m. to Elliott Hall this Saturday, brought to life through vocalists, dancers and a live chamber orchestra. The Mark Morris Dance Group will discuss the ins and outs of the aesthetics in a pre-show talk at 7 p.m. in the Mechanical Engineering Building, Room 1103. Below, Laurel Lynch, lead performer playing dual roles, Dido and the Sorceress, answers questions to give you a sense of what you’ll be able to take away from the show and pre-show.
