Trumpeter Christopher Martin,  principal trumpet of the Chicago Symphony since 2005,  has resigned his position with the CSO in order to become principal trumpet with the New York Philharmonic.  I had the great pleasure of interviewing Mr. Martin a couple of years ago when he appeared as guest soloist with the Lake Geneva Symphony.   He proved to be a friendly, engaging guest and I loved speaking with him.  Here is part one of our conversation, in which we talk – among other things – about his childhood and how he first began taking trumpet lessons.
