New online: When Karajan took over a concerto on live TVmain
At a Paris concert in 1978 Herbert von Karajan replaced the pianist Alexis Weissenberg in the slow movement of Mozart’s 21st piano concerto K467.
The pair were intimate friends and the substitution (after 14:20 on video) appears to have been prearranged.
Karajan’s playing is very slow and imperfect, with more than a few slurred notes. Weissenberg returned in the finale.
This televisied concert takes place a few months before the conductor suffered a hushed-up stroke.
