This season marked the 75th Anniversary of the Celebrity Series of Boston, founded by Aaron Richmond, whose widow, Nancy Richmond Winsten, sponsors the piano events and is still a familiar attendee. I have a deep sense of nostalgia about the Celebrity Series. The very first concert I ever attended in Boston was with the Budapest String Quartet (my favorite quartet) in 1962. It was my first year of graduate school (I was a very young grad student) and I was living on a $1500 a year scholarship. I had neither time nor money for anything as frivolous as a chamber music concert. But I had to go. The Jordan Hall box office told me the performance was sold out... unless I was willing to take a cheap stage seat. So there I was, sitting a few feet away from the Budapest Quartet playing Haydn, Mozart, and Schubert. It remains one of the greatest concerts I ever heard in my life.
