Because some of these venues also run lighting rigs in the order of magnitude of 100KW and probably don't have the space/money/expertise to install a UPS with that power capacity.

Would lights need to be run on the UPS, or just the audio equipment?

A single loudspeaker in a line array can draw up to 24A at 240V [0]. Even a very small rig of 6 speakers would require over 30kw. A 50kw UPS [1] can be purchases for a very affordable $25,000 in 2016 [2]. When building a performance art venue in 1960 or today, a technical ground is a much more suitable option than a UPS.
