Some Japanese musicians are making a "music dictionary" or something (I don't know the details), one of them asked me how you guys call こけらおとし in English.
こけらおとし means the (formal) opening of a new theater
こけらおとし【柿落とし】 を英語で表現すると - Yahoo!辞書
actually they are looking for a word or 2 to explain こけらおとし.
They want to know if there is any special "word" (slang? Jargon?)used by artist/singers/musicians/actors.
If not then can we say like...
the first perfomance of the new theater,
the first show at the new theater,
the first play of the new theater
the first concert of the new hall.
..... like that???
