Alfred Brendel is retiring. When I was 19, his recital was the first classical concert I ever paid money to see (~$19 at Carnegie -- last row, or next to). Thanks to the Times archives, Allan Kozinn's review of that evening remains. Sadly, what I remember most was a sallow little geezer in front of me squirming throughout the Schubert sonata (Not Brendel, but a ticketholder). Actually I do remember the way Brendel's hands didn't seem to move during the Haydn and Mozart. Now, nearly a decade since, Brendel's farewell concert in Chicago will take place this Sunday at Orchestra Hall. And the same lineup of composers are to be programmed as when I saw him in '00. Today Alex Ross notes he performed the Schubert G-flat Impromptu (Op. 90) as an encore from a few weeks ago; according to Kozinn on my night, he did so as well. If he's maddeningly conservative, he's forgiven through grace.
