Leslie Odom Jr., of “Hamilton” fame, will perform with the San Diego Symphony on July 7 and 8. The San Diego Symphony’s Bayside Summer Nights 2017 concert series promises such established stars as Tony Bennett and New Orleans legend Dr. John, as well as up-and-coming artists like Leslie Odom Jr., fresh from the Broadway smash musical “Hamilton.” Megan Swan, the symphony’s associate director of artistic planning, also predicts Harry Potter sightings and whiffs of Aqua Net hair spray.
