Okay, here's my first swing at this one:
* The band is called The Sane Abandoned.
* Looking up YouTube, the picture appears under one of their songs titled "KATE".
* One of the more popular current horror actresses is named KATE Siegel.
* Kate Siegel has appeared in recent horror films: Oculus and Ouija: Origin of Evil. But, more importantly, she has appeared in 11 episodes of the hit Netfix TV series The Haunting of Hill House.
* The opening paragraph of the Shirley Jackson novel which inspired the TV series reads as thus:
“No live organism can continue for long to exist sanely under conditions of absolute reality; even larks and katydids are supposed, by some, to dream. Hill House, not sane, stood by itself against its hills, holding darkness within; it had stood for eighty years and might stand for eighty more. Within, walls continued upright, bricks met neatly, floors were firm, and doors were sensibly shut; silence lay steadily against the wood and stone of Hill House, and whatever walked there, walked alone.”
* Interesting that the opening paragraph mentions "sane" twice since the clue is a picture of "The Sane Abandoned" and the paragraph is literally intimating that Hill House is sane abandoned.
* The Haunting of Hill House was a popular rumor for HHN29. So it wouldn't surprise me if it's still a popular rumor for this year.
* So, my first blush guess (given Legacy's post from yesterday) is that it's a clue to The Haunting of Hill House RUMOR.
