Apropos of Mr. Lipstone's famous condemnation, "Goldenage" Marco has just uncovered this interesting summary of the dates when MR's music really did sound forth in New York's leading hall: https://www.carnegiehall.org/PerformanceHistorySearch/#!composer=8145
I'm pleased to recall the several occasions when I was present:
Jan 28, 1969
Oct 15, 1976
Apr 22, 2001
Oct 1, 2007
I regret that I just missed the Heifetz-Piatigorsky performance in 1964, when my interest in the classical repertory was only just budding.
