addressed a crowd gathered / gathering

[Shooting Stars]

On Thursday 19 April, one of the world’s last remaining absolute monarchs addressed a crowd gathered at a small sports stadium in southern Africa.(The cost of changing a country's name)
"Gather" can be either transitive or intransitive when it means "come together". I was wondering if I can use both the present participle and the past participle to modify a noun. For example in the sentence mentioned above, can I use "gathering" instead of "gathered"?
Thank you.

Either would be grammatical in that sentence, but they don't mean the same thing. 'Gathered' is a past participle and 'gathering' is a present participle.

Either would be grammatical in that sentence, but they don't mean the same thing.

Could you tell me what the difference between the two versions is?

Hello.

gathered- the crowd has already gathered by the time he begins to speak
gathering- the crowd is in the process of gathering while he speaks

Is that clear?

I understand now. Thank you.
