There was something about this in the past year somewhere else (NYT? BBC?),
about how there was a series of "time capsules" buried under the Paris
opera, some recordings on glass (?)

WASHINGTON - The muffled sounds from more than 150 years ago resemble the
"wa wa" of the unseen teacher in the Peanuts cartoons. It would be
impossible to know that someone was playing the coronet and guitar, although
other fragments, from a dramatic speech from Shakespeare's Othello, might be
discerned if you knew the lines by heart in French.
