From reading the post alone, it doesn't sound like Aurora or London Grammar are involved at all; I think they're just referenced to give context for Roy Kerr. Have you seen anything else to suggest they had a hand in it?
No I haven't. I guess I miss understood the text in the post. Thank you! I will delete this thread.
Edit: I have deleted my post that have started this thread, though the thread is not deleted in general. Maybe the stuff of the forum can delete this thread. My apologies to everyone for my miss understanding regarding this IG post.
