I should like to point out something about
the Boston-centered Me2/Orchestra in particular.

This cause appeals to amateur musicians who also happen to be
professionals in the business of mental health care,
and so the orchestra has a fair number of members who are
psychiatrists, psychotherapists, social workers, nurses, medical technicians, and the like --
as they support the removal of the stigma from the mental health issue.
And Boston, as a major metropolitan center
and the home of so many colleges and universities,
has a particularly large number of such practitioners.
