As much as I admired Rena Mueller's fabulous tribute on NYU's webpage, and agreeing w/ her on Robert's lecture on the Berg Concerto (which I heard that week with the Concertgebouw & Perlman at Fisher Hall), and all the other things she mentioned, also remembered like they were yesterday, I have to add my fondest memory of his lectures: the Adagio from Bruckner 8th, a work as monumental as the 186 story Burj in Dubai.
45 minutes of laying out a GPS with chalk on chalkboard of what we were about to hear. Then he put the record on. With Robert, you didn't need a score. His map on the board was all you required.
And he circled each tonal shift, harmonic milestone, as it occurred in real time. This was his method, and it worked, BIG TIME.
At the two (one false, to trick you!) climaxes near the end, he circled his notes furiously, as we listened to the fortissimo orchestra climax(es), and, as he did so, we wanted to jump out of our seats.
Then the slow, laborious descent into one of music's most poetic pianissimo declines, one of the greatest ever penned by a western composer.
I remember that day 40 years ago, like it was yesterday.
Robert, you made an enormous impression on us!
