I saw a lot shows in old warehouses, and played shows in old warehouses.
First thing you do is check the exits and make sure tgey are clear.
The Ghost Ship was a firetrap with blocked exits, a poorly constructed interior structure, stairs made of pallets, and extremely questionable wiring.
While we played some sketchy dives, way would we have played that joint.
Part of the appeal is that it's in an improbable place, a place where such a thing shouldn't be. The light show, the music, in there? It seemed cool at the time, apparently still does to some.
