Efe Baltacıgil, associate principal cellist of the Philadelphia Orchestra, has accepted the principal cellist spot with the Seattle Symphony Orchestra. He starts this fall with the opening of the 2011–2012 season.
Officially, Baltacıgil is taking a leave of absence from Philadelphia for 2011-12, giving him the option of returning the following season. This kind of testing-the-waters period is customary in the orchestral world.
