Machanism/item strapped above audience in a music venue
I saw this at a music venue. It was strapped onto railings above the audience facing the stage. Says "kick out", is attached by zip ties, looks like a tube wrapped in a durable plastic coat, and looked like it might have a wire running to it.
Image is not flipped, I had to turn away from the stage to see this, so I suppose if unfurled it would correctly face the audience when they look at the stage.
I'm just saying that unless unfurling it would rotate it horizontally, the "kick" will remain on the right and looks like it would be meant to be viewed by those up "there," behind the sign.
That makes sense. For extra context, the balcony its attached to is a gantry only for sound engineers, Containing only the lights and equipment etc. Audience is only below.
There appears to be another line of text under it in your picture, although not enough of it is there to be legible. I'm sure it has other content as well -- more text, logos, a photo, whatever.
