The executive director of the Louisville Orchestra has announced his resignation, just one month after the orchestra ended a bitter stalemate with its musicians and settled on a plan to avert bankruptcy. Tim King, a 44-year-old who has worked in the arts since 1981, insists that the decision to leave is his own, and came only in response to a job offer he couldn’t refuse. “A self-described passionate gardener, he’ll be going into sales at a nursery and landscaping company operated by former orchestra development director Michael Oppelt.”
