That's a sobering thought. So worthy of reflection.
I can think of at least two published recordings in which there are
serious electronic noises. First: J. Strauss II: Emperor Waltzes --
Frederick Stock/Chicago Symphony Orchestra. Victor (single, two sides)
78 7653. Recorded December 23, 1930, in Orchestra Hall.
The original issue was very short-lived, perhaps because of loud
electronic popping noises on side two. They sound very much like the
malfunction of something. Perhaps tubes. My owned and examined copies
have shown take 2 for that side. The record was reissued after the
war. It and even some early copies might have utilized take 3, and
that might have been quiet, but I have not obtained copies that might
contain that take.
Other extraneous, evidently electronic noises include the weird
occasional "bonging" sounds in such early electrical British Columbia
recordings as Sir Henry Wood's Beethoven Eroica.
