Two great musicians. Gould plays and Bernstein conducts from the first movement of J S Bach "Concerto for Keyboard in D Minor."
from the CBC Archives: "On April 25, 1962 there is a highly publicized incident between Glenn Gould and conductor Leonard Bernstein at Carnegie Hall in New York. In later years, this night would be cited as one of the reasons the very private Gould would stop giving public performances.
In this clip, Bernstein disassociates himself and the New York Philharmonic from Gould's unorthodox interpretation of Brahms's First Piano Concert in D minor.
"Bernstein prefaces the concert with the famous phrase, "Don't be frightened, Mr. Gould is here..." Bernstein tells the audience that while he respects Gould, he strongly disagrees with his interpretation of Brahms piece. Following the introduction, Gould plays the first and last movement of the concerto at an extraordinarily slow tempo."
This tape I gather is from an earlier broadcast that same month for the Canadian Broadcasting Company.
