>>78560114ライブ (n) is a loanword in Japanese from the English word "live" (adj), but it entered Japanese with only the sense of "concert" and lost the "being performed now" sense that it has in English. Japanese agencies re-exported it for English-speaking audiences without regard to the confusion it would cause when people read the word with the English adjectival sense.
You should read "live" (n) as a loanword from Japanese that means "concert".
