Yuri Temirkanov’s departure from the Baltimore Symphony is only the latest leaving by senior leadership. “When some of the most seasoned and effective employees left, the blithe word from on high was, ‘No one is irreplaceable.’ Management expressed no concern for the drain in institutional memory or community and patron connections that those resignations signified. Losing Temirkanov, whose guidance has generated a higher technical level and remarkably communicative spirit within the orchestra, may likewise be shrugged off as an inevitable, not-to-worry development. But only those who have never truly recognized what this conductor had to offer could be feeling blase today.”
