The NYPO has had well-publicized problems with finding a new principal clarinetist. Now they've announced the pending retirement of concertmaster Glenn Dicterow at the end of the 2013-14 season. He'll be moving back to Southern California, whence he comes, and will be starting to teach at the Thornton School of Music (USC) in the fall of 2013.
He's been NYPO concertmaster since 1980, having previously held the same chair at the LA Phil. These will be big, big shoes to fill.
