When orchestras go looking for a new chief executive, the first question that must be answered is whether the ensemble wants to hire someone with intimate knowledge of the music world, or a numbers expert with proven experience balancing budgets. The Fort Worth (Texas) Symphony, however, has decided to go with some of each talent in hiring Katherine Akos as its new CEO. Akos is a violinist, daughter of a Chicago Symphony musician, and also an experienced fund-raiser in the non-profit world. She joins an orchestra which is in comparatively good financial shape, but is struggling to avoid a deficit for the current season.
