Anonymousa new performance of a play that has not been performed for ...
Why does it have to be 'a performance' and not 'the performance'?
It's just an abstract definition of a term. No specific performance has been referred to previously, so
the is not appropriate. The idea is any new performance, no matter when or where it occurs.
Any of these performances would be considered a revival, not just a specific, previously mentioned one.
AnonymousA new attire of a person can do wonders for his appearance.
attire is uncountable. To make an example with a, change it to
suit, which is countable:
A new suit can do wonders for a person's appearance.
Again, the is not appropriate because no specific new suit has been referred to previously. The intent is to express the idea of any new suit, no matter which new suit, and not one specific suit.

college education is normally used as a countable compound noun; you will need an article.
