“Traditionally, orchestras organize seasons horizontally because attendance is built on season subscriptions. Seasons often have themes that develop across the entire year, not quite as cohesively as an episodic TV show like “Lost” but designed to have some connection between concerts or to build up to key soloists or symphony works. But the recent explosion in entertainment has challenged that approach. Today’s world is driven by the event; live music must compete with a host of options from Netflix to sports to touring shows.”
