A billboard has appeared in central London today, appearing to tease something Bring Me The Horizon related:
The billboard reads "DO YOU WANNA START A CULT WITH ME?" with a phone number.
Note that the symbols in the top corners are a logo used by Bring Me The Horizon previously.
If you call the number, you're connected to a line which offers ridiculous spiritual advice and guidance before eventually playing a distorted clip of what is assumedly brand new Bring Me The Horizon music.
