Quoting from the Orchestra's web site: “Looking back over these decades I am filled with gratitude for the extraordinary artistic partnership I have had with the members of the Orchestra and for the warm and generous style of music making we have shared with all of our audiences,” said Michael Tilson Thomas.
Thomas will be 75 at the time he leaves the podium, and will be marking his 25th year with the San Francisco Symphony.
