Internal politics and bitter rivalries are roiling the Honolulu Symphony, which has seen its CEO, its president and several key board members resign in recent months. At the heart of the chaos appears to be a dispute over who should fill the post of president of the organization, and the infighting has spilled out into public, with the orchestra’s board chair now offering to be the next one to step down. The symphony has been plagued by budget problems in recent years, and its musicians reopened their contract and accepted major salary cuts last season. Meanwhile, former Pittsburgh Symphony CEO Gideon Toeplitz has agreed to become the HSO’s interim president, and will be in place within a few weeks.
