HELP! Anyone know what club this could be?

A few nights ago i walked past this place in Hongdae, a few doors down from the clothing shop ‘what it isn’t’ and there was a huge hand drawn poster advertising “post punk goth new wave djs” on a locked gate under this sign. There was no info on the hand written sign, and i’ve never seen the gate open! I also can’t find any results for clubs or bars on naver or google maps at this building.

Anybody have any leads on where this DJ could be held? Or if it even still exists?
