was this true in orchestra history?

[Fearless]

i heared in my orchestra class that
in one concert
from a orchestra performers
that they didnt play for a whole 10 min
beacouse they wanted ppl to know what they wanted from the war
silence and stuff
im not sure if that was true
they played songs after this
and then in one song the condocter raised his hands wit his baton and then lower then adn the whole orchestra went silent for a long time
then when it was over
everyone in the audience stan up and clapped
so was that true
