I got hired around ten years ago to record a woman who turned out to have
played flute in both the NBC Symphony and the New York Philharmonic where
she met her husband who played clarinet. Before leaving, we sat down with
the couple and had a conversation about the recording and broadcasting of
those orchestras. After some wonderful anecdotes about Toscanini and
Stokowski, I was shocked to hear them say they believed "recordings improved
so much after the modern technique of using lots of microphones instead of
only one started to be used."
