The lyrics to 魅惑劇 by ALI PROJECT contain the following fragment:
I would take the bolded 閉じ to be either continuative or a nominalization, except in the first case there isn't any verb that the sentence/statement could continue onto (is it perhaps just an artistic omission?) and as for the second I haven't really encountered 閉じ used to mean 閉じること searching around on the web. I'm also not sure whether it could be used with を in such a case.
Is it one of the things listed or something else entirely? What nuance does it carry?
