Simplifying a sentence [closed]

The logistics were those of a very large army, which indeed it was, battalions of extras and theatrical performers for the biggest sound set ever conceived.

Could someone simplify this sentence please?


I would move the topic of the sentence up, and break it up into a separate sentence as well. You bury the lede after a convoluted introduction:

The sound set was the biggest ever conceived. Its logistics were like those of a very large army, which indeed it was, with battalions of extras and theatrical performers.
